Genesis 15

Genesis 15 records a pivotal covenant ceremony wherein the Lord addresses Abram's fear and uncertainty regarding his progeny and inheritance by formalizing the promise of a vast seed and the land of Canaan. This chapter formally establishes the justification of Abram by faith alone, setting a canonical precedent for righteousness before God.

• The Lord appears in a vision to address Abram's fear, identifying Himself as a shield and great reward.
• Abram expresses his grief and confusion over his childless state, questioning the status of his inheritance.
• The Lord clarifies that an heir from Abram's own body will arise, and confirms this by pointing to the innumerable stars.
• Abram believes the Lord, and this faith is reckoned to him as righteousness.
• The Lord initiates a formal covenant ceremony, involving divided sacrifices, signifying His solemn commitment to give the land of Canaan to Abram's descendants.
• God reveals the future suffering of Abram's seed in a foreign land followed by their deliverance, concluding with the symbolic passing of the smoking furnace and burning lamp between the pieces.

• Abram's fear vs. God as shield (v. 1)
• Eliezer of Damascus as the steward (v. 2)
• The stars as a metaphor for the number of seed (v. 5)
• The ritual of cutting animals in half (v. 10)
• The prophecy of 400 years of affliction (v. 13)
• The smoking furnace and burning lamp (v. 17)

This chapter is fundamental to redemptive history as it explicitly defines justification by faith (v. 6), a verse later used by Paul to establish the gospel (Romans 4). It also establishes the unconditional nature of God's covenant with Israel, as God alone passes through the pieces, signaling His unilateral commitment to the promise.

God establishes His covenant not through human merit or effort, but through His own unilateral commitment and promise, which requires only the trusting faith of the recipient to be reckoned as righteousness.

The chapter moves from dialogue to covenant ritual, progressing from a verbal promise to a formal, self-maledictory oath by God that guarantees the future of the covenant people and the land.

• God promises to be Abram's shield and exceeding great reward (v. 1).
• God promises an heir from Abram's own bowels (v. 4).
• God promises that Abram's seed will be as innumerable as the stars (v. 5).
• God promises the land of Canaan as an inheritance to Abram's seed (v. 7, 18).
• God promises the future deliverance of Abram's seed from a foreign land of affliction (v. 14).
• God promises that Abram himself will die in peace at a good old age (v. 15).

• Fear not (v. 1).
• Look now toward heaven, and tell (count) the stars (v. 5).
• Take me an heifer of three years old, and a she goat of three years old, and a ram of three years old, and a turtledove, and a young pigeon (v. 9).

• The seed of Abram will be strangers in a land not theirs and serve and be afflicted for 400 years (v. 13).

• Abram lived in a patriarchal society where a son was vital for the continuation of the family name and protection of property.
• The ritual of cutting animals (v. 10) was a known ancient Near Eastern practice for treaty making, where the parties walking between the pieces invoked a curse upon themselves if they broke the agreement.

• Damascus, mentioned in v. 2, was a significant city; Abram's concern regarding Eliezer reflects the custom of adopting a household steward as a legal heir if no biological children were present.

• This chapter follows the rescue of Lot and the interaction with Melchizedek (Gen 14), providing a spiritual resolution to the physical conflict previously endured.

• This passage is foundational to the New Testament's doctrine of justification. Paul uses Genesis 15:6 in Romans 4:3 and Galatians 3:6 to prove that salvation has always been by faith, not by adherence to the Law.
• The promise of the seed refers ultimately to Christ (Gal 3:16).
• The prophecy of the 400 years of affliction is historical, fulfilled later in the Egyptian bondage and exodus (Exodus 1:1-12:41).

• The language of 'passing through' or 'cutting' a covenant is echoed in Jeremiah 34:18-19, which clarifies the meaning of the ritual Abram performed.

• The word 'believed' [H539, אָמַן] suggests an active, firm trust or reliance upon God's word, as one would lean on a sturdy pillar.
• The word 'counted' [H2803, חָשַׁב] implies a judicial reckoning or an accounting process, where God acts as a judge crediting righteousness to Abram's account.
• The term 'covenant' [H1285, בְּרִית] appears here as 'made' (lit. cut) a covenant, referencing the act of dividing the animals (v. 18).

• The text mentions Abram 'drove them [the fowls] away' (v. 11), illustrating that believers often have to actively protect their devotion to God from intrusive distractions.
• Note the profound silence of Abram during the covenant ritual; he is the recipient of God's unilateral action, not an equal participant in 'cutting' the treaty.

• There is historical debate regarding the '400 years' (v. 13). Some interpret this as a literal period of affliction, while others reconcile it with the '430 years' mentioned in Exodus 12:40, considering the timeframe of the entire sojourn in a foreign land. Matthew Henry observes that God gives a general time frame for the affliction to humble his people but does not explicitly detail every moment of their suffering.
