Deuteronomy 17

The text moves from the individual worshiper to the judiciary, and finally to the national head of state, demonstrating that the Law of the Lord is binding upon every stratum of Israelite society.

• The king who submits to the Law and the Lord will prolong his days in his kingdom (v20).

• Bring the idolater to the gates to be stoned (v5).
• Follow the judgment of the priests and the judge (v10).
• Do not turn from the sentence given by the central court (v11).
• The king must write a copy of the Law (v18).
• The king must read the Law all the days of his life (v19).

• Do not sacrifice anything with a blemish (v1).
• Do not kill based on the testimony of only one witness (v6).
• Do not multiply horses, wives, or silver (v16-17).
• Do not set a foreigner as king (v15).

• This law was given while Israel was yet in the wilderness, preparing to enter a land where the surrounding nations practiced absolute monarchies where kings were often viewed as divine or semi-divine.
• The requirement for a central place of judgment anticipates the later establishment of Jerusalem as the religious and judicial capital.

• The prohibition against 'multiplying horses' was a rejection of the militaristic self-reliance common in Ancient Near Eastern empires that relied on chariotry and foreign alliances.
• The requirement for the king to be a 'brother' (an Israelite) rejected the practice of appointing vassal kings from foreign powers.

• This chapter is central to the legal corpus of Deuteronomy (chapters 12-26), transitioning from the religious life (chapters 12-16) to the civil and political life of the nation.

• The desire for a king in 1 Samuel 8 acts as a historical pivot where the people shift from the ideal of theocracy to the reality of monarchy; Matthew Henry observes that 'God's choice, if we can but know it, should direct, determine, and overrule ours,' noting that the king was not to be a lawmaker, but a law-keeper.
• The New Testament reflects on Christ as the ultimate, sinless King who never turned from the Law, contrasting with the human kings of Israel who failed to keep these specific prohibitions.

• The language of 'not turn to the right hand or to the left' is echoed in Joshua 1:7, reinforcing the necessity of adherence to the written Law.

• The word 'abomination' (תּוֹעֵבַה [H8441]) implies moral disgust; it is used to describe both the unworthy sacrifice and the act of idolatry, highlighting that both violate the holiness required by the Covenant (בְּרִית [H1285]).
• The term 'presumptuously' (used in the context of v12) conveys a defiant attitude—a deliberate choice to reject authority—rather than simple ignorance or error.

• The king's mandate to write a copy of the Law (v18) was intended to humble him; he was to be a subject of the Torah, not its author.
• The repetition of the word 'gates' (sha'ar [H8179]) connects the everyday life of the people in their local towns with the supreme authority of the central sanctuary.

• There is historical scholarly discussion regarding 'the place the Lord shall choose' (v8); while historical, archaeological, and textual evidence points to the centralized sanctuary (eventually Jerusalem), the text emphasizes the divine choosing of the location rather than the geography itself.
