"I am a shield to you." The chapter opens with a formula that will run through the whole prophetic tradition — "the word of Jehovah came to Abram" (devar-YHWH), its first appearance in the Bible — and its first words answer the chapter before. "I am a shield" (magen) picks up the root of Melchizedek's blessing, where God "delivered" (miggen) Abram's foes (14:20); and "your reward shall be very great" answers Abram, who had just refused to let the king of Sodom make him rich (14:23). The man who would take nothing from Sodom is told his reward comes from God. (The reward clause is slightly open: KJV reads "I am… thy exceeding great reward" — God himself as the reward; Mister keeps the plainer "your reward shall be very great," with God as the giver.)

"Eliezer of Damascus." Then the first crack in Abram's faith: he is childless (ariri), and his heir is a servant. The Hebrew naming him — ben-mesheq beiti, roughly "the son of the acquisition of my house" — is genuinely obscure, and every version wrestles with it (KJV "the steward of my house is this Eliezer"). The sense is clear even where the words aren't: a house-born servant, not a son, stands to inherit. And "Lord Jehovah" (Adonai YHWH) sets the title Adonai, "Lord," before the name itself — the reading the ASV uses for this compound (the versions that keep the name hidden print "Lord" with their small-cap substitute for it instead). On the choice to print the name as Jehovah, see the Ask Mr. Librarian page.

The stars. God takes Abram outside and turns the impossible into a promise: "count the stars, if you are able… so shall your offspring be." To a childless man, the whole night sky.

Verse 6 — "counted to him as righteousness." One of the most consequential sentences in the Bible, and one to state without settling. "Believed" is he'emin, from aman, the root behind amen — not bare agreement but trust, leaning one's weight on God's word. "He counted it to him as righteousness": Jehovah reckons that trust as right standing — tzedaqah, righteousness — granted, not earned. Every version renders it closely (KJV "counted it to him for righteousness," NIV "credited it to him as righteousness").

The one honest thing a note must add: the New Testament itself reads this verse two ways. Paul makes it the charter of justification by faith apart from works — "Abraham believed God, and it was credited to him as righteousness," so the promise comes by faith, not law-keeping (Romans 4; Galatians 3). James cites the very same verse to argue that faith is completed by works, pointing to Abraham's later offering of Isaac: "was not Abraham justified by works… and the Scripture was fulfilled that says, 'Abraham believed God'" (James 2). Whole traditions have divided over which emphasis governs. The Hebrew of Genesis 15:6 states the fact — trust, reckoned as righteousness — and leaves the argument to those who cite it; so does this note.

"How am I to know?" "I am Jehovah, who brought you out from Ur of the Chaldeans" — the Chaldeans are again the anachronism flagged at 11:31 (they reached Ur only much later); a later hand has updated the old city's name. And notice the tension: the man who "believed" in verse 6 now asks, "how am I to know that I shall possess it?" Faith and a request for assurance sit side by side, unembarrassed — and God answers not with a rebuke but with a covenant.

The pieces. The strange ritual: a heifer, a goat, and a ram, each three years old (meshulleshet — "three-year-old," or possibly "three of each"; the versions differ), plus two birds. Abram cuts them in two (vayvatter, from batar — this is "the covenant of the pieces," brit bein ha-betarim) and lays the halves facing each other; the birds he leaves whole. Birds of prey descend, and Abram — a small vivid detail — drives them off. This is an ancient covenant rite: the parties would pass between the divided animals, invoking the halves on themselves — "so may I be cut apart if I break faith."

The deep sleep. As the sun sets, a deep sleep (tardemah) falls on Abram — the very word used for the sleep God laid on the human in the garden before making the woman from his side (2:21); it is the sleep in which God does the work. With it comes "a dread, a great darkness."

The four hundred years. God foretells the whole of the coming bondage: Abram's offspring will be strangers in a land not their own, enslaved and afflicted, four hundred years — the Egyptian slavery, named centuries before it begins — then judgment on that nation, and an exodus "with great possessions" (the plunder of Egypt, already promised here). Two honest wrinkles: the "four hundred years" is "four hundred and thirty" in Exodus 12:40, and the "fourth generation" of verse 16 doesn't obviously square with four centuries — the numbers are round and schematic, and the traditions harmonize them variously.

"The iniquity of the Amorite is not yet complete." The most arresting line in the chapter, and its reason for the long delay: the conquest waits four hundred years because the wickedness of the land's peoples has not yet "filled up." It is a statement of divine patience — and, read honestly, the Bible's own framing of the later conquest as judgment on a filled measure of evil rather than mere conquest. It is a hard verse, and this translation lets it stand as it is, hard.

The God who walks the pieces alone. When full dark falls, "a smoking oven and a flaming torch" — fire, the sign of God's presence, as at the bush and on Sinai — pass between the pieces. And here is the heart of it: Abram is asleep. Only God walks the aisle of cut animals. In the ordinary rite both parties pass through, binding both; here God binds himself alone, taking the self-curse on his own head — the covenant rests on God's faithfulness, not Abram's. It is, quietly, the most one-sided promise in the book.

"Jehovah cut a covenant." Hebrew karat brit, "cut" — the same verb as the cut animals; a covenant is always "cut." The land is granted "from the river of Egypt to the great river, the Euphrates" (the "river of Egypt" is debated — not the Nile but more likely the Wadi el-Arish on Egypt's frontier), and its current peoples are listed, ten of them — the Rephaim among them, the giants struck back in 14:5. "I have given" — a completed-tense verb for a thing still centuries off: as good as done.
