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: 19 the Kenites, the Kenizzites, the Kadmonites, 20 the Hittites, the Perizzites, the Rephaim, 21 the Amorites, the Canaanites, the Girgashites, and the Jebusites.”

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.
