Numbers 21

Hello, partner! Ready to dive into some truly fascinating territory today? Numbers 21 is a powerhouse of a chapter, packing victories, complaints, divine healing, and major conquests into a relatively short space. What's truly non-obvious here, I think, is how the Torah seems to collapse time, weaving together events that span decades, challenging our linear understanding of narrative, and forcing us to grapple with the deeper theological threads at play.

Context

To really appreciate Numbers 21, it helps to zoom out a bit and remember where we are in the grand narrative of Bamidbar. The Israelites have been wandering for nearly forty years, a generation has passed, and they are now on the cusp of entering the promised land. This isn't just a geographical journey; it's a spiritual transformation. The wilderness has been a crucible, forging a people from disparate tribes into a nation ready to inherit God's promise. Yet, as we'll see, the old habits of complaint and doubt still linger, even as new challenges and opportunities for conquest arise.

The chapter itself functions as a pivot point. It marks the final leg of their wilderness journey, geographically positioning them on the eastern bank of the Jordan, looking towards Canaan. But it also marks a shift in their engagement with the surrounding peoples. No longer solely fleeing or being tested, they are now actively engaging in warfare, initiating conquests that will define their future territorial claims. The inclusion of ancient poems ("The Book of the Wars of G-d," the "Song of the Well," and the "Bards' Recitation" about Sihon) isn't just literary flourish; it imbues these events with a timeless, epic quality, suggesting that these battles and divine interventions were sung about and remembered long after they occurred, becoming foundational narratives for the nascent nation. These embedded texts serve as echoes of a living, developing tradition even within the Torah itself.

Text Snapshot

Let's ground ourselves in a few key lines from Numbers 21:

When the Canaanite, king of Arad, who dwelt in the Negeb, learned that Israel was coming by the way of Atharim, he engaged Israel in battle and took some of them captive. Then Israel made a vow to GOD and said, “If You deliver this people into our hand, we will proscribe their towns.” GOD heeded Israel’s plea and delivered up the Canaanites; and they and their cities were proscribed. So that place was named Hormah.

They set out from Mount Hor by way of the Sea of Reeds to skirt the land of Edom. But the people grew restive on the journey, and the people spoke against God and against Moses, “Why did you make us leave Egypt to die in the wilderness? There is no bread and no water, and we have come to loathe this miserable food.” GOD sent seraph serpents against the people. They bit the people and many of the Israelites died. The people came to Moses and said, “We sinned by speaking against GOD and against you. Intercede with GOD to take away the serpents from us!” And Moses interceded for the people. Then GOD said to Moses, “Make a seraph figure and mount it on a standard. And anyone who was bitten who then looks at it shall recover.” Moses made a copper serpent and mounted it on a standard; and if someone was bitten by a serpent, they would look at the copper serpent and recover.

Israel now sent messengers to Sihon king of the Amorites, saying, “Let me pass through your country... We will follow the king’s highway until we have crossed your territory.” But Sihon would not let Israel pass through his territory. Sihon gathered all his troops and went out against Israel in the wilderness. He came to Jahaz and engaged Israel in battle. But Israel put them to the sword, and took possession of their land, from the Arnon to the Jabbok... (Numbers 21:1–9, 21–24, Sefaria)

This chapter is a masterclass in contrasts and thematic density. Let's unpack three significant insights.

Insight 1: Structural Juxtaposition – The Whirling Cycles of Triumph and Tribulation

One of the most striking features of Numbers 21 is its rapid, almost dizzying, oscillation between high points of divine favor and deep troughs of human failure. Look at the immediate sequence:

• Numbers 21:1-3: Israel faces a challenge from the King of Arad, makes a vow to God, God answers, Israel achieves a decisive victory, and the place is named Hormah, signifying "utter destruction" – a testament to their success and dedication. This is a moment of agency and triumph, where Israel's initiative is met with divine assistance.
• Numbers 21:4-9: Immediately following this victory, the narrative shifts. "They set out from Mount Hor... But the people grew restive on the journey, and the people spoke against God and against Moses, 'Why did you make us leave Egypt to die in the wilderness?'" This complaint, mirroring earlier episodes in the wilderness, triggers divine punishment: "G-d sent seraph serpents against the people. They bit the people and many of the Israelites died." This is a profound plunge from victory to despair, followed by repentance and an unusual act of divine healing via the copper serpent.

This isn't merely a chronological recounting of events; it's a deliberate narrative choice that highlights Israel's complex spiritual state. On one hand, they demonstrate a capacity for faith, strategic thinking, and successful engagement with enemies, as seen with Arad. On the other hand, a slight geographical inconvenience ("to skirt the land of Edom") or discomfort ("miserable food") can send them spiraling back into the same complaints that plagued the previous generation.

The juxtaposition serves to underscore a persistent tension in Israel's journey: the constant struggle between their divinely-ordained destiny and their human frailty. The Arad victory shows what they can be when united in faith and purpose. The serpent incident, immediately thereafter, reveals the ever-present danger of spiritual backsliding, even after witnessing miracles and achieving triumphs. It suggests that external victories do not automatically translate into internal spiritual fortitude. The wilderness, even as it draws to a close, continues to test their resolve and purify their faith. The cyclical nature of complaint, punishment, repentance, and deliverance seen here is not just a repetition of past events but a reiteration of the fundamental lesson: reliance on God is paramount, and even small comforts can become grounds for major spiritual failure if perspective is lost. The Torah, in this structure, is teaching us that spiritual growth isn't linear, but often a series of forward steps and backward slips, requiring constant vigilance and renewed commitment.

Insight 2: Key Term – "Proscribe" (חרם - cherem) and the Weight of Vows

The term cherem (חרם), translated here as "proscribe" or "utterly destroy," is a powerful and significant concept in the Torah. In Numbers 21:2, Israel makes a vow: "If You deliver this people into our hand, we will proscribe (וְהַחֲרַמְתִּי) their towns." Following the victory, verse 3 states: "G-d heeded Israel’s plea and delivered up the Canaanites; and they and their cities were proscribed (וַיַּחֲרֵם). So that place was named Hormah (חָרְמָה)."

The root cherem implies something set apart, removed from common use, often for dedication to God, leading to its destruction or utter devotion. It’s distinct from simple conquest or spoils of war. The footnote refers to Joshua 6:24, where Jericho's silver, gold, and vessels of copper and iron were dedicated to the treasury of the House of G-d. This suggests that cherem isn't merely annihilation but a form of sanctified destruction, where the objects or places are rendered unusable for common human benefit and dedicated to God, often through destruction.

What's striking here is that Israel initiates this vow. Unlike other instances where cherem is a divine command (e.g., in Deuteronomy regarding idolatrous cities), here it's a condition set by the people to secure divine aid. This highlights the profound gravity and binding nature of vows (nedarim) in Jewish thought. Once made, especially to God, they carry immense weight. God "heeded Israel's plea" – implying that the vow itself was a significant factor in securing divine favor.

The naming of the place "Hormah" (חָרְמָה), directly derived from the root cherem, permanently memorializes this act of dedication and destruction. It marks the site as a place where Israel's commitment to God, expressed through a vow of cherem, was both tested and fulfilled. This concept pushes us to consider the power of human initiative in covenantal relationship with God. When Israel commits wholeheartedly, even to a severe measure, God responds. It also sets a precedent for the gravity of future wars of conquest in the land, where the concept of cherem would play a role, not just as a military strategy but as a theological statement of God's absolute claim over the land and its former inhabitants. The very act of naming the place Hormah ties the physical landscape to a spiritual act of dedication, making the land itself a witness to Israel's covenant with God. This isn't just a battle; it's a foundational act of national identity rooted in a solemn promise.

Insight 3: Tension – The Paradox of the Copper Serpent: Divine Healing through a Forbidden Form

Perhaps one of the most theologically challenging episodes in this chapter is the account of the copper serpent:

• Numbers 21:8: "Then G-d said to Moses, 'Make a seraph figure and mount it on a standard. And anyone who was bitten who then looks at it shall recover.'"
• Numbers 21:9: "Moses made a copper serpent and mounted it on a standard; and if someone was bitten by a serpent, they would look at the copper serpent and recover."

On the surface, this seems like a straightforward miracle. But upon deeper reflection, it presents a profound theological tension, particularly in light of the Second Commandment against making graven images (Exodus 20:4) and the repeated warnings against idolatry. God commands Moses to create an image of the very creature that is inflicting the punishment. How can a physical object, especially one that resembles a "seraph" (which can also imply a fiery, venomous serpent), be an instrument of divine healing without bordering on idolatry?

The Mishnah, in Rosh Hashanah 3:8, provides crucial insight into this paradox: "Was it the serpent that killed or the serpent that kept alive? Rather, when Israel looked upward and subjected their hearts to their Father in Heaven, they were healed; otherwise, they perished." This explanation clarifies that the copper serpent itself possessed no inherent magical or healing properties. Its function was symbolic, a divinely appointed catalyst for faith. The act of "looking at it" was not an act of worshipping the serpent, but an act of looking through it and beyond it to God, expressing repentance and trust in His power to heal.

The tension lies in the risk inherent in such a symbol. While intended to foster faith, a physical object representing a deity or power could easily be misinterpreted and become an object of worship itself. Indeed, centuries later, King Hezekiah had to destroy this very copper serpent (called Nehushtan) because "the Israelites had been offering sacrifices to it" (2 Kings 18:4). This shows that the risk of misinterpretation was not hypothetical; it became a reality.

This episode is a powerful lesson in the nature of divine mediation and human perception. God chooses a surprising and potentially dangerous medium to teach His people a fundamental truth: healing and salvation come from Him alone, and even the most counterintuitive means can be His instrument. The paradox forces Israel to engage in a sophisticated act of faith – to use a physical object without attributing power to it, to look at an earthly representation while directing their hearts heavenward. It’s a profound teaching on the role of kavannah (intention) in ritual and the constant vigilance required to distinguish between a means to God and God Himself. It tests their understanding of divine transcendence and immanence, revealing that even in the midst of the mundane or the fearsome, God's presence and power can be found, but only if one looks with the right heart.

Two Angles

The opening verses of Numbers 21 present a rich interpretive challenge, particularly regarding the identity of "the Canaanite, king of Arad" and the timing of the cherem vow's fulfillment. Rashi and Ramban, two giants of medieval commentary, offer distinctly different perspectives, showcasing how geographical, chronological, and linguistic nuances can lead to profound theological disagreements.

Rashi's Interpretation: The Deceptive Amalekite and Immediate Fulfillment

Rashi (Rabbi Shlomo Yitzchaki, 11th century France), grounded in Midrashic tradition, offers a striking interpretation of the "Canaanite, king of Arad." He states:

Rashi on Numbers 21:1:1: "He heard that Aaron had died and that the clouds of glory had disappeared and he believed that now he was at liberty to wage war against Israel... Amalek was from olden times a whip for chastising Israel..." Rashi on Numbers 21:1:2: "THE INHABITANT OF THE SOUTH COUNTRY — This was Amalek, as it is said, (Numbers 13:29), 'Amalek was the inhabitant of the south country'. But he purposely changed his speech, talking in the “Canaanite” tongue, so that Israel might thereby be misled and would pray to the Holy One, blessed be He, that he should give the Canaanites into their power, whilst really they were not Canaanites, and their prayer would be ineffectual against the Amalakites. But Israel perceived that their clothing was as the clothing of Amalakites whilst their language was the language of Canaan; they thereupon said, 'Let us pray against our enemies in general terms (without mention of any name), as it is stated (v. 2) that they said, 'if Thou wilt indeed give this people into my hand'." Rashi on Numbers 21:1:4: "AND CAPTURED FROM THEM A CAPTIVE — it was only one maid servant."

For Rashi, the "Canaanite" was not a true Canaanite but Amalek, Israel's perennial enemy, disguised. This deception was strategic: by speaking Canaanite, Amalek hoped to trick Israel into making a specific vow against "Canaanites," which would be ineffective against Amalekites, thereby negating their prayer. However, Israel, discerning the deception (by their clothing), wisely made a generic vow against "this people." This explains the unusual phrasing of the vow. Furthermore, the initial defeat was minimal – "only one maidservant" was taken captive, suggesting that Israel's setback was not significant enough to be considered a true defeat in the divine sense. Rashi implies that the "proscription" and naming of "Hormah" occurred immediately and fully in Moses's time, as a direct consequence of this specific battle and vow.

Ramban's Interpretation: The Geographically Nuanced Canaanite and Collapsed Time

Ramban (Rabbi Moshe ben Nachman, 13th century Spain), known for his emphasis on peshat (plain meaning) alongside midrash, takes a very different approach, focusing heavily on geographical and chronological consistency within the biblical narrative:

Ramban on Numbers 21:1:1: "The correct interpretation appears to me to be that this king of Arad dwelt in the south on the western side of the Jordan, in the land of Canaan near the Jordan... and he heard from afar of the coming of the children of Israel, so he [the king] came by the way of Atharim to the plains of Moab to fight there against Israel." Ramban on Numbers 21:1:1 (continued): "Scripture continued by relating here that Israel also laid their cities waste when they came into the land of Canaan, after the death of Joshua, in order to fulfill the vow which they had made, and they called the name of the cities Hormah... It is with reference to this that it is stated in the Book of Judges, 'And Judah went with Simeon his brother, and they smote the Canaanites that inhabited Zephath, and utterly destroyed it. And he called the name of the city Hormah' (Judges 1:16-17)." Ramban on Numbers 21:1:3: "According to the plain meaning of Scripture, the sense of the verse is that these Canaanites did not kill any of the Israelites, but took a few of them captive, and when G-d [later on] delivered them into their hands, they brought them all back, and not a single one of them was missing."

Ramban insists that the "Canaanite, king of Arad" was indeed a genuine Canaanite, whose territory was west of the Jordan, in Canaan proper, near Hebron. He argues that this king "came by the way of Atharim" (which Onkelos renders as "the way of the spies") to attack Israel on the eastern side of the Jordan. This resolves the geographical difficulty of a Canaanite king from west of the Jordan fighting Israel while they are east of it.

Crucially, Ramban posits that the Torah here "collapses time." While the people of Arad were defeated in Moses's time, the destruction of their cities and the full fulfillment of the cherem vow (Numbers 21:3) actually occurred much later, after Joshua's death, by the tribes of Judah and Simeon, as recorded in Judges 1:16-17. Moses, writing the Torah under divine inspiration, included this future event in a past tense because "there is no difference in time for G-d." Ramban also offers a secondary explanation that a preliminary destruction happened then, and the final destruction of the cities happened later. He takes "took some of them captive" literally, suggesting a more significant, though not fatal, initial setback than Rashi's "one maidservant."

The Core Contrast

The fundamental difference lies in their approach to narrative time and identity. Rashi, drawing on Midrash, prioritizes the immediate theological lesson of Amalek's enduring enmity and Israel's sagacity, even if it requires identifying "Canaanite" as a disguise. The fulfillment is immediate. Ramban, however, prioritizes geographical and historical consistency, leading him to a more complex understanding of the Torah's prophetic nature, where future events are woven into the present narrative. For him, the fulfillment of the vow is split across generations, with the Torah presenting a divine, non-linear perspective. These contrasting views illuminate the richness of biblical commentary, where a single verse can open doors to divergent understandings of history, prophecy, and identity.

Practice Implication

The episode of the copper serpent (Numbers 21:8-9) offers a profound and perennial lesson that directly shapes our daily practice and decision-making, particularly concerning the role of physical objects in spiritual life and the importance of kavannah (intention).

God commanded Moses to create a physical object—a copper serpent—and instructed the bitten Israelites to look at it for healing. On the surface, this could appear to be a form of idolatry or magic, especially given the strict prohibitions against making graven images. However, as the Mishnah in Rosh Hashanah 3:8 clarifies, "Was it the serpent that killed or the serpent that kept alive? Rather, when Israel looked upward and subjected their hearts to their Father in Heaven, they were healed; otherwise, they perished."

This teaching underscores a critical principle in Judaism: mitzvot (commandments) often involve physical actions or objects, but their efficacy comes not from the object itself, but from the spiritual intention and connection they facilitate with God. The copper serpent was a means to an end, a focal point that redirected the Israelites' attention and faith from their suffering and the venomous snakes to the ultimate Healer. The danger, as history later showed with King Hezekiah destroying the Nehushtan (2 Kings 18:4) because people had begun worshipping it, is when the means becomes the end—when the object itself is imbued with power, rather than serving as a conduit to the Divine.

In our daily lives, this translates into how we approach religious rituals and objects. Take, for example, tefillin (phylacteries), mezuzah, or a siddur (prayer book). These are physical objects we interact with regularly. The lesson of the copper serpent teaches us that the power is not in the leather straps of the tefillin themselves, nor in the parchment of the mezuzah, nor the pages of the siddur. Their significance lies in their capacity to elevate our thoughts, focus our intentions, and connect us to God. When we don tefillin, it's not the act of wrapping alone, but the kavannah—the conscious awareness of God's unity, His commandments, and our commitment to Him—that transforms a physical action into a spiritual experience. Similarly, kissing a mezuzah upon entering a room is not an act of venerating the object, but an acknowledgment of God's presence and our covenant.

This understanding profoundly shapes decision-making around spiritual engagement. It encourages us to cultivate a deeper kavannah in all mitzvot, recognizing that the physical act is a gateway to the spiritual. It warns against superficial religiosity, where one performs rituals mechanically without inner focus, effectively reducing powerful spiritual tools to mere talismans. It also informs how we teach and transmit Judaism to others, emphasizing the meaning and purpose behind traditions, rather than just the rote performance.

Furthermore, this principle extends beyond ritual objects to our entire relationship with the material world. Just as a serpent figure could be transformed into an instrument of healing, so too can mundane aspects of life be sanctified when approached with proper intention. Eating, working, resting – all can become acts of worship if performed with the awareness of God's presence and purpose. The copper serpent reminds us that the Divine can manifest in surprising ways, even through the very things that cause us fear or discomfort, challenging us to look beyond the surface and find God in all things.

Chevruta Mini

Here are two questions to prompt further thought and discussion, surfacing some interesting tradeoffs:

Question 1: The Paradox of the Symbol

If the act of looking at the copper serpent was meant to inspire looking heavenward and recognizing God as the ultimate Healer, why did God command a physical representation of the very creature causing harm, rather than a more abstract symbol of divine power or simply instructing them to pray directly? What are the tradeoffs in using a potentially idolatrous symbol for a holy purpose, especially given its eventual fate as Nehushtan?

Question 2: The Gravity of the Vow

Israel's vow to cherem the cities of Arad was a condition for securing divine assistance and victory. Is this an instance of the people dictating terms to God, or an expression of extreme commitment that God then honored? What are the ethical and theological implications of a community making such a severe vow in wartime, and what tradeoffs does it present for future generations (e.g., Ramban's idea of the vow's fulfillment being spread across different eras)?

Takeaway

Numbers 21 reveals Israel's paradoxical journey towards nationhood, marked by both Divine intervention and persistent human struggle, where faith, vows, and even physical objects become complex conduits for salvation and self-definition.
