7 Then the Lord told him, "I am the Lord who brought you out of Ur of the Chaldeans to give you this land as your possession." 8 But Abram replied, "O Sovereign Lord, how can I be sure that I will actually possess it?" 9 The Lord told him, "Bring me a three-year-old heifer, a three-year-old female goat, a three-year-old ram, a turtledove, and a young pigeon." 10 So Abram presented all these to him and killed them. Then he cut each animal down the middle and laid the halves side by side; he did not, however, cut the birds in half. 11 Some vultures swooped down to eat the carcasses, but Abram chased them away.

12 As the sun was going down, Abram fell into a deep sleep, and a terrifying darkness came down over him. 13 Then the Lord said to Abram, "You can be sure that your descendants will be strangers in a foreign land, where they will be oppressed as slaves for 400 years. 14 But I will punish the nation that enslaves them, and in the end they will come away with great wealth. 15 (As for you, you will die in peace and be buried at a ripe old age.) 16 After four generations your descendants will return here to this land, for the sins of the Amorites do not yet warrant their destruction."

17 After the sun went down and darkness fell, Abram saw a smoking firepot and a flaming torch pass between the halves of the carcasses. 18 So the Lord made a covenant with Abram that day and said, "I have given this land to your descendants, all the way from the border of Egypt to the great Euphrates River- 19 the land now occupied by the Kenites, Kenizzites, Kadmonites, 20 Hittites, Perizzites, Rephaites, 21 Amorites, Canaanites, Girgashites, and 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.
