I Samuel 10

Sugya Map & Snapshot

The Conceptual Landscape of I Samuel 10

The narrative of Saul’s elevation to the monarchy in I Samuel 10 serves as the foundational locus classicus for the metaphysics and halakhic mechanics of Jewish political sovereignty. The sugya presents three primary conceptual axes:

• The Dual-Anointment Dichotomy: The tension between private, charismatic initiation via flask (pach) and public, bureaucratic validation via lottery (goral).
• The Nature of Ontological Transformation: The transition of Saul's persona from a seeker of lost livestock to a vessel of divine ecstasy (vayehafekh lo Elohim lev acher).
• The Halakhic Status of the Saulide Dynasty: The constitutional distinction between a permanent dynastic monarch (melekh) and a conditional, non-hereditary ruler (nagid).

Nafka Mina (Practical and Conceptual Ramifications)

1. The Halakhic Validity of a Lottery (Goral): Does a lottery function as an active kinyan (acquisition/designation) or merely as a gilluy da'at (revelation of a pre-existing divine choice)?
2. The Definition of a King: Does a temporary ruler possess the legal prerogatives of the monarchy (e.g., taxation, conscription, capital punishment for rebellion) under the framework of Mishpat HaMelukha?

Text Snapshot: I Samuel 10:1 & 10:9

וַיִּקַּ֨ח שְׁמוּאֵ֜ל אֶת־פַּ֧ךְ הַשֶּׁ֛מֶן וַיִּצֹּ֥ק עַל־רֹאשׁ֖וֹ וַיִּשָּׁקֵ֑הוּ וַיֹּ֕אמֶר הֲל֗וֹא כִּֽי־מְשָׁחֲךָ֧ יְהוָ֛ה עַל־נַחֲלָת֖וֹ לְנָגִֽיד׃

"Samuel took a flask of oil and poured some on his head and kissed him, and said, 'Has not the Lord anointed you ruler over His inheritance?'" — I Samuel 10:1

וְהָיָ֗ה כְּהַפְנֹת֤וֹ כִתְפוֹ֙ לָלֶ֣כֶת מֵעִם־שְׁמוּאֵ֔ל וַיַּהֲפָךְ־ל֥וֹ אֱלֹהִ֖ים לֵ֣ב אַחֵ֑ר וַיָּבֹ֛אוּ כָּל־הָאֹת֥וֹת הָאֵ֖לֶּה בַּיּ֥וֹם הַהֽוּא׃

"And it was, as he turned his shoulder to go from Samuel, God turned him another heart; and all those signs came to pass that day." — I Samuel 10:9

Grammatical and Lexical Nuances

• פַּךְ (Pach): A narrow-necked clay flask, contrasting sharply with the קֶרֶן (Keren), the horn used for David. The root of pach implies dripping or leaking, denoting a finite, precarious measure.
• לְנָגִֽיד (Le-Nagid): Samuel pointedly avoids the term מֶלֶךְ (Melekh) in his opening declaration. A nagid is a prince, a military commander, or a trustee—an office of stewardship rather than absolute sovereign possession.
• וַיַּהֲפָךְ־ל֥וֹ אֱלֹהִ֖ים לֵ֣ב אַחֵ֑ר (Vayehafekh lo Elohim lev acher): Not merely a psychological shift, but a passive-transitive transformation of the lev (the seat of intellect and will), preparing Saul for a new metaphysical reality.

Readings

The Rishonim and Acharonim divide sharply on the mechanics of Saul's transition to power. By analyzing the provided commentaries, we can map out three distinct conceptual models of this transformation.

1. The Metaphysical-Dualism Model: Malbim

The Malbim (Malbim on I Samuel 10:1:1) addresses the dual nature of Samuel’s initiation ritual—the pouring of oil and the subsequent kiss:

ויקח שמואל וכו' על ידי המשיחה המשיך עליו רוח גבורה ועז מלך... ועל ידי הנשיקה שהיא התדבקות רוחא ברוחא המשיך עליו שפע קדש שבזה הכין אותו לנבאות אחר כך עם בני הנביאים "Samuel took [the flask of oil] etc. Through the anointing, he drew down upon him a spirit of heroism and kingly strength... and through the kiss, which is the cleaving of spirit to spirit, he drew down upon him a holy flow, thereby preparing him to prophesy afterward with the sons of the prophets."

Malbim splits the coronation into two distinct spiritual operations:

• The Anointing (Meshichah): This acts upon the physical and political realm. It infuses Saul with ruach gevurah (the spirit of fortitude) and oz melekh (monarchic strength). This is the external, executive capacity required to lead armies and administer justice.
• The Kiss (Neshikah): This acts upon the metaphysical realm. Drawing on Kabbalistic motifs of itdabkut rucha be-rucha (the adhesion of spirit to spirit), the kiss is a transmission of intellectual and spiritual charisma. It bridges the gap between Saul’s mundane soul and the prophetic plane.

Furthermore, Malbim addresses the political necessity of the private ceremony, quoting the Abarbanel (Maharia):

ומה שלא משחו בפרהסיא באר מהרי"א כדי שיוכל להפיל גורל אח"ז ואם היה נמשח בפרהסיא היה הגורל למותר בעיני העם, והיו חושדים אותו שהטה את הגורל בערמה על האיש אשר משח "And that which he did not anoint him in public, the Maharia explained: so that he could cast lots afterward. For if he had been anointed in public, the lottery would have been superfluous in the eyes of the people, and they would have suspected him [Samuel] of deceptively rigging the lottery in favor of the man he had already anointed."

Here, Malbim introduces a crucial political-legal dynamic: the lottery was not a divine farce, but a necessary mechanism of public validation. Had the anointing been public, the subsequent lottery would have been dismissed as a rigged performance. The private anointing established the de jure metaphysical reality before God, while the public lottery established the de facto political consensus before the nation.

Finally, Malbim distinguishes between the terms Nagid and Melekh:

מבואר כי לכן משחו בצנעה בל ירגישו שלא נמשח רק לנגיד... תפס נגיד ולא מלך באשר לא הובטח לו המלכות בירושה כדרך הנמשח בשמן הקדש "It is clear that for this reason he anointed him in secret, so they would not perceive that he was only anointed as a ruler (nagid)... he employed the term nagid and not melekh because the kingdom was not promised to him as an inheritance, in the manner of one anointed with the holy anointing oil."

Thus, the use of the flask (pach) and the title nagid are intrinsically linked. They signal a conditional, non-hereditary appointment. Saul is a steward, not the founder of an eternal dynasty.

2. The Constitutional-Materialist Model: Radak and Metzudat David

In contrast to the Malbim’s highly metaphysical reading, the Radak and the Metzudat David focus on the material symbols of the coronation and their constitutional implications.

Radak (Radak on I Samuel 10:1:1) addresses the physical nature of the oil used:

לא היה זה השמן המשחה כי לא היו משוחים ממנו אלא מלכי בית דוד אבל שמן אפרסמון היה ואמרו שאול ויהוא שנמשחו בפך לא נמשכה מלכותן דוד ושלמה שנמשחו בקרן נמשכה מלכותן "This was not the sacred anointing oil, for only the kings of the House of David were anointed with it; rather, it was balsam oil (shemen afarsimon). And they [the Sages] said: Saul and Jehu, who were anointed from a flask (pach), their kingdom was not prolonged; David and Solomon, who were anointed from a horn (keren), their kingdom was prolonged."

Radak establishes a sharp halakhic distinction between two types of oils and vessels:

• The Vessel (Pach vs. Keren): The clay flask (pach) is fragile, easily shattered, and closed off. It represents a temporary, fragile regime. The horn (keren) is organic, durable, and represents continuous growth and power.
• The Substance (Shemen Afarsimon vs. Shemen HaMishchah): Saul was not anointed with the unique Shemen HaMishchah formulated by Moses in the wilderness. Instead, he was anointed with Shemen Afarsimon (balsam oil), a high-quality but common aromatic oil. This material difference reflects a constitutional reality: Saul's kingship was a functional presidency, whereas David’s kingship was a metaphysical, dynastic covenant.

Radak (Radak on I Samuel 10:1:2) then pivots to the midrashic taxonomy of the kiss:

בדרש כל נשיקות הם של תיפלות חוץ מג' נשיקות נשיקה של גדולה נשיקה של פרקים נשיקה של פרישות, נשיקה של גדולה ויצוק על ראשו וישקהו... "In the Midrash: All kisses are of frivolity, except for three: the kiss of greatness, the kiss of meeting, and the kiss of parting. The kiss of greatness is [derived from]: 'And he poured [oil] upon his head and kissed him'..."

This Midrashic framework, cited by Radak, strips the kiss of any romantic or mundane connotation. It is a formal, legal category—neshikah shel gedulah (a kiss of elevation/office). It is the ancient near-eastern equivalent of a formal oath of fealty, wherein the prophet, acting as the divine representative, abdicates his sole leadership and transfers authority to the new king.

Metzudat David (Metzudat David on I Samuel 10:1:1) reinforces this literalist, functional reading of the opening verse:

הלא. באמת הדבר אשר משחך ה׳ על ידי "Is it not so? Indeed, the matter is true that God has anointed you through my hand."

The Metzudat David reads the interrogative halo ("is it not?") not as a question of doubt, but as a strong assertion of certainty. Samuel is assuring Saul that despite the secrecy and the simplicity of the flask, the coronation is an absolute, binding metaphysical fact.

---

3. The Psychological-Developmental Model: Ralbag

The Ralbag (Ralbag on I Samuel 10:1:1) takes a distinct rationalist approach, focusing on the epistemological challenges faced by Saul:

והנה לקח שמואל פך השמן ויצק על ראש שאול למשחו למלך על ישראל ונתן לו אותות כדי שיאמין כי הממלכה תהיה לו והאות היותר חזק מהם הוא ההפך לו לב אחר והתנבאו עם נביאים והוא לא נסה קודם זה להיות לו יד ושם בנבואה "And behold, Samuel took the flask of oil and poured it upon Saul's head to anoint him as king over Israel, and he gave him signs so that he would believe that the kingdom would be his. And the strongest sign among them was the turning of another heart to him and his prophesying with the prophets, when he had never previously attempted to have any hand or renown in prophecy."

Ralbag identifies the core problem of Saul’s transition as one of epistemological doubt. Saul was a pragmatist, a farmer's son preoccupied with the immediate reality of lost donkeys. To suddenly assume the mantle of national sovereignty required a radical restructuring of his subjective reality.

For Ralbag, the three signs (otot) are not mere magic tricks; they are a graduated educational curriculum designed to build Saul's self-confidence:

1. The first sign (the two men at Rachel's tomb): Solves his immediate, mundane anxiety regarding the donkeys. This proves that Samuel's vision extends to the physical world.
2. The second sign (the three men at the Tabor tree): Introduces him to the realm of social prestige. Strangers voluntarily hand him bread, recognizing his royal dignity before he is publicly announced.
3. The third and greatest sign (the band of prophets at the Hill of God): This is the ultimate proof. His sudden entry into prophetic ecstasy (vayehafekh lo Elohim lev acher) demonstrates that his very cognitive apparatus has been elevated by divine decree. Since Saul had no prior training in the prophetic arts (lo nisa kodem zeh), this sudden transformation could only be explained by a direct, divine restructuring of his mind.

Friction

Kushya 1: The Epistemological and Halakhic Redundancy of the Goral (Lottery)

If Saul was already anointed by Samuel via direct divine command (backed by three undeniable prophetic signs, including his transformation into "another man"), why was a public lottery (goral) at Mizpah necessary?

If the lottery is the formal mechanism of public designation, then the private anointment is halakhically premature or merely advisory. If, however, the private anointment is the true source of kingship (as Malbim suggests, infusing him with ruach gevurah), then the lottery is a theatrical performance that risks making the divine selection look like a game of chance.

Terutz A: The Political-Societal Resolution (Malbim/Abarbanel)

As cited in the Malbim, the goral was not designed to inform Samuel or Saul of God's choice; rather, it was a concession to human skepticism.

Had Samuel simply presented Saul and declared, "This is the king whom God chose through my prophecy," the people would have revolted, claiming nepotism or political manipulation. The goral was an objective, public demonstration of divine selection that bypassed human bias. The lottery forced the hand of public consensus by showing that the divine finger pointed to the exact same individual who had been anointed in secret.

Terutz B: The Lomdish Resolution (The Gavra/Cheftza Distinction)

We can resolve this tension by introducing a conceptual distinction between the Gavra (the person of the king) and the Cheftza (the objective legal status of the monarchy).

The private anointing by Samuel transformed the Gavra of Saul. It infused him with the personal charisma, the ruach gevurah, and the intellectual capacity (lev acher) required to be a leader. However, the legal entity of the monarchy—the covenantal relationship between the king and the nation—requires a public bilateral agreement.

The public lottery and the subsequent recording of the "rules of the monarchy" (mishpat hamelukha) in a book I Samuel 10:25 created the Cheftza of the kingdom of Israel. Without the public ceremony at Mizpah, Saul was a highly qualified individual (Gavra), but he did not yet possess the formal legal status of a king (Cheftza) over the nation.

---

Kushya 2: The Ontological Status of Saul's Prophecy

How could Saul, who had no prior prophetic training, suddenly experience prophetic ecstasy?

According to the Rambam in Mishneh Torah, Foundations of the Torah 7:1, prophecy does not occur haphazardly. It requires a rigorous regimen of intellectual, moral, and imaginative perfection:

אין הנבואה חלה אלא על חכם גיבור ועשיר... ויתגבר על יצרו תמיד "Prophecy only rests upon a wise, strong, and wealthy person... who constantly overcomes his inclination."

Saul, at this point in his life, was intellectually unproven and preoccupied with mundane agricultural concerns. How does his sudden transformation not violate the fundamental Rambamian axiom that prophecy requires systematic preparation?

Terutz A: The Radical Metaphysical Miracle (Ralbag)

The Ralbag concedes that under natural conditions, Saul was entirely unfit for prophecy. This is precisely why the text emphasizes: "Is Saul also among the prophets?" I Samuel 10:11. This exclamation was not just a proverb of surprise; it was a recognition of a metaphysical anomaly.

God performed a radical, instantaneous miracle (nes) by bypassing the natural developmental stages, temporarily restructuring Saul's brain (vayehafekh lo Elohim lev acher) to allow him to receive the divine flow. This was a temporary, emergency measure (horat sha'ah) to establish his authority.

Terutz B: The Environmental-Charismatic Resolution (Rambam, Guide for the Perplexed)

The Rambam himself resolves this difficulty in the Guide for the Perplexed (II:45), where he categorizes Saul’s experience not as actual prophecy (nevuah in the strict sense), but as the first and lowest degree of divine inspiration:

המדרגה הראשונה היא שילווה לאיש עזר אלוהי שיניעהו ויזרזהו לעשות טובה גדולה בעלת ערך... וזה נקרא רוח ה' "The first degree is when a divine assistance accompanies a person, moving and encouraging him to perform a great and significant good... and this is called 'the Spirit of the Lord.'"

Rambam explains that the "spirit of God" that came upon Saul was a state of intense charismatic enthusiasm, similar to the spirit that seized Samson or Gideon. It did not communicate specific theological truths or laws (which would require intellectual perfection). Rather, it was a state of heightened emotional and active courage triggered by his proximity to the band of prophets (chevel nevi'im).

Prophecy, in this context, was contagious. By entering the physical presence of trained prophets who were playing musical instruments, Saul was swept up in their spiritual energy. This was an environmentally-induced ecstasy rather than an intrinsic prophetic achievement.

Intertext

1. The Anointing of David vs. The Anointing of Saul

To understand the constitutional limitations of Saul's appointment, we must contrast I Samuel 10:1 with the subsequent anointing of David in I Samuel 16:13:

Metric	Saul's Anointing (I Samuel 10:1)	David's Anointing (I Samuel 16:13)
Vessel	Flask (Pach - פך)	Horn (Keren - קרן)
Location	Private, isolated path	Public, "in the midst of his brothers"
Result	Temporary, conditional (Nagid)	Eternal, dynastic covenant (Melekh)

This textual contrast is analyzed in the Talmud in Horayot 11b:

תנו רבנן: אין מושחין את המלכים אלא מן הקרן... שאול ויהוא שנמשחו מן הפך לא נמשכה מלכותן, דוד ושלמה שנמשחו מן הקרן נמשכה מלכותן "Our Rabbis taught: Kings are anointed only from a horn... Saul and Jehu, who were anointed from a flask, their kingdom was not prolonged; David and Solomon, who were anointed from a horn, their kingdom was prolonged."

The Halakha here codifies a physical symbol into a legal reality. The keren represents permanence because it is an organic, growing part of a living animal. The pach is a synthetic, fragile vessel of clay.

The choice of vessel is a prophetic prediction of the longevity of their respective dynasties. Saul’s kingship was a functional, temporary measure to transition Israel from the chaotic era of the Judges to a centralized state. It was never intended to be permanent.

---

2. The Conflict of the "Rules of the Monarchy"

In I Samuel 10:25, Samuel writes down the "rules of the monarchy" (mishpat hamelukha) and deposits them before God:

וַיְדַבֵּ֨ר שְׁמוּאֵ֜ל אֶל־הָעָ֗ם אֵ֚ת מִשְׁפַּ֣ט הַמְּלֻכָ֔ה וַיִּכְתֹּ֣ב בַּסֵּ֔פֶר וַיַּנַּ֖ח לִפְנֵ֣י יְהוָ֑ה...

This acts as a direct counterpoint to two other biblical passages:

1. The Torah's King Companion: Deuteronomy 17:14-20, which severely restricts the king's power (prohibiting him from acquiring excess horses, wives, or gold, and requiring him to write a personal Sefer Torah).
2. Samuel's Anti-Monarchic Manifesto: I Samuel 8:11-18, where Samuel warns the people that a king will seize their fields, conscript their children, and tax them heavily.

How do we reconcile these three distinct legal frameworks of Jewish monarchy?

רב יהודה אמר שמואל: כל האמור בפרשת מלך - מלך מותר בו. רב אמר: לא נאמרה פרשה זו אלא לאיים עליהם "Rav Yehuda said in the name of Shmuel: Everything stated in the chapter of the king [I Samuel 8]—the king is permitted to do. Rav said: This chapter was only stated to frighten them."

The Rambam Mishneh Torah, Kings and Wars 4:1 codifies the view of Shmuel: the king has the absolute halakhic authority to draft citizens, seize property for military necessity, and levy taxes.

Thus, the mishpat hamelukha written down by Samuel in I Samuel 10:25 was a constitutional document. It balanced the absolute executive powers detailed in Chapter 8 with the ethical, Torah-subjugated limitations detailed in Deuteronomy 17. It was placed "before God" as a covenantal treaty, warning the king that his authority was contingent upon his submission to divine law.

Psak / Practice

The narrative of Saul's selection and coronation establishes key precedents in the realm of halakhic authority and political theory.

1. The Appointment of a King (Halakhic Requirements)

The Rambam codifies the process of establishing a king based on the events in I Samuel 10:

אין מעמידין מלך בתחילה אלא על פי בית דין של שבעים זקנים ועל פי נביא, כיהושע שמינהו משה רבינו ובית דינו, וכשאול ודוד שמינם שמואל הרמתי ובית דינו.

"We do not appoint a king initially except by a court of seventy elders [the Sanhedrin] and by a prophet, as Joshua was appointed by Moses and his court, and as Saul and David were appointed by Samuel of Ramah and his court." — Mishneh Torah, Kings and Wars 1:3

From here we derive that Jewish political authority is not purely populist. It requires a tripartite consensus:

• Divine Selection: Transmitted via a prophet (Navi).
• Judicial Validation: Approved by the supreme court (Sanhedrin).
• Popular Acclamation: Confirmed by the public assembly (as the people shouted, "Long live the king!" in I Samuel 10:24).

2. The Halakhic Status of Non-Davidic or Modern Governments

Does the distinction between Saul’s conditional appointment (pach/nagid) and David’s eternal dynasty (keren/melekh) mean that non-Davidic rulers lack halakhic legitimacy?

The Rambam addresses this directly:

מלכי בית דוד הם העומדים לעולם... אבל אם יעמוד מלך משאר ישראל ותהיה המלכות לו, הרי זה מלך לכל דבריו.

"The kings of the House of David stand forever... but if a king should arise from the rest of Israel and the kingdom is his, he is a king in all regards." — Mishneh Torah, Kings and Wars 1:8

Even though Saul's dynasty was temporary and lacked the eternal covenant of David, during his tenure he possessed the full halakhic status of a king. This has significant contemporary ramifications:

• The Authority to Wage War: A non-Davidic government (including the Hasmonean kings or a democratically elected Israeli government) possesses the legal authority of the king regarding military mobilization and national defense.
• Taxation and Civil Law: The principle of Dina d'Malchuta Dina (the law of the land is the law) applies to Jewish rulers in Eretz Yisrael. This authority is derived from the functional model of kingship established by Saul, which is rooted in executive utility rather than divine lineage.

Takeaway

The transition of Saul from a private citizen to the first king of Israel teaches that Jewish political authority requires a synthesis of divine selection, internal psychological readiness, and formal public-legal validation. One cannot rule by charisma alone; sovereignty must be bound by constitutional law and accepted by the nation.
