5 Yahweh brought him outside, and said, “Look now toward the sky, and count the stars, if you are able to count them.” He said to Abram, “So shall your seed be.” 6 He believed in Yahweh; and he reckoned it to him for righteousness.

7 He said to him, “I am Yahweh who brought you out of Ur of the Chaldees, to give you this land to inherit it.” 8 He said, “Lord Yahweh, how will I know that I will inherit it?” 9 He said to him, “Bring me a heifer three years old, a female goat three years old, a ram three years old, a turtledove, and a young pigeon.” 10 He brought him all of these, and divided them in the middle, and laid each half opposite the other; but he didn’t divide the birds. 11 The birds of prey came down on the carcasses, and Abram drove them away.

12 When the sun was going down, a deep sleep fell on Abram. Now terror and great darkness fell on him. 13 He said to Abram, “Know for sure that your seed will live as foreigners in a land that is not theirs, and will serve them. They will afflict them four hundred years. 14 I will also judge that nation, whom they will serve. Afterward they will come out with great wealth, 15 but you will go to your fathers in peace. You will be buried in a good old age. 16 In the fourth generation they will come here again, for the iniquity of the Amorite is not yet full.”

17 It came to pass that, when the sun went down, and it was dark, behold, a smoking furnace, and a flaming torch passed between these pieces. 18 In that day Yahweh made a covenant with Abram, saying, “To your seed I have given this land, from the river of Egypt to the great river, the river Euphrates:

Commentary on Genesis 15:2-6

(Read Genesis 15:2-6)

Though we must never complain of God, yet we have leave to complain to him; and to state all our grievances. It is ease to a burdened spirit, to open its case to a faithful and compassionate friend. Abram's complaint is, that he had no child; that he was never likely to have any; that the want of a son was so great a trouble to him, that it took away all his comfort. If we suppose that Abram looked no further than outward comfort, this complaint was to be blamed. But if we suppose that Abram herein had reference to the promised Seed, his desire was very commendable. Till we have evidence of our interest in Christ, we should not rest satisfied; what will all avail me, if I go Christless? If we continue instant in prayer, yet pray with humble submission to the Divine will, we shall not seek in vain. God gave Abram an express promise of a son. Christians may believe in God with respect to the common concerns of this life; but the faith by which they are justified, always has respect to the person and work of Christ. Abram believed in God as promising Christ; they believe in him as having raised him from the dead, Romans 4:24. Through faith in his blood they obtain forgiveness of sins.

Commentary on Genesis 15:7-11

(Read Genesis 15:7-11)

Assurance was given to Abram of the land of Canaan for an inheritance. God never promises more than he is able to perform, as men often do. Abram did as God commanded him. He divided the beasts in the midst, according to the ceremony used in confirming covenants, Jeremiah 34:18,19. Having prepared according to God's appointment, he set himself to wait for the sign God might give him. A watch must be kept upon our spiritual sacrifices. When vain thoughts, like these fowls, come down upon our sacrifices, we must drive them away, and seek to attend on God without distraction.

Commentary on Genesis 15:12-16

(Read Genesis 15:12-16)

A deep sleep fell upon Abram; with this sleep a horror of great darkness fell upon him: a sudden change. The children of light do not always walk in the light. Several things were then foretold. 1. The suffering state of Abram's seed for a long time. They shall be strangers. The heirs of heaven are strangers on earth. They shall be servants; but Canaanites serve under a curse, the Hebrews under a blessing. They shall be suffers. Those that are blessed and beloved of God, are often sorely afflicted by wicked men. 2. The judgment of the enemies of Abram's seed. Though God may allow persecutors and oppressors to trample upon his people a great while, he will certainly reckon with them at last. 3. That great event, the deliverance of Abram's seed out of Egypt, is here foretold. 4. Their happy settlement in Canaan. They shall come hither again. The measure of sin fills gradually. Some people's measure of sin fills slowly. The knowledge of future events would seldom add to our comfort. In the most favoured families, and most happy lives, there are so many afflictions, that it is merciful in God to conceal what will befall us and ours.

Commentary on Genesis 15:17-21

(Read Genesis 15:17-21)

The smoking furnace and the burning lamp, probably represented the Israelites' severe trials and joyful deliverance, with their gracious supports in the mean time. It is probable that this furnace and lamp, which passed between the pieces, burned and consumed them, and so completed the sacrifice, and testified God's acceptance of it. So it intimates that God's covenants with man are made by sacrifice, Psalm 50:5. And we may know that he accepts our sacrifices, if he kindles in our souls pious and devout affections. The bounds of the land granted are stated. Several nations, or tribes, are spoken of, that must be cast out to make room for the seed of Abram. In this chapter we perceive in Abram faith struggling against, and triumphing over, unbelief. Wonder not, believers, if you meet with seasons of darkness and distress. But it is not the will of God that you should be cast down: fear not; for all that he was to Abram he will be to you.
