1After these things Yahweh’s word came to Abram in a vision, saying, “Don’t be afraid, Abram. I am your shield, your exceedingly great reward.”
2Abram said, “Lord Yahweh, what will you give me, since I go childless, and he who will inherit my estate is Eliezer of Damascus?” 3Abram said, “Behold, you have given no children to me: and, behold, one born in my house is my heir.”
4Behold, Yahweh’s word came to him, saying, “This man will not be your heir, but he who will come out of your own body will be your heir.” 5Yahweh 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 your offspring will be.” 6He believed in Yahweh, who credited it to him for righteousness. 7He said to Abram, “I am Yahweh who brought you out of Ur of the Chaldees, to give you this land to inherit it.”
8He said, “Lord Yahweh, how will I know that I will inherit it?”
9He 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.” 10He brought him all these, and divided them in the middle, and laid each half opposite the other; but he didn’t divide the birds. 11The birds of prey came down on the carcasses, and Abram drove them away.
12When the sun was going down, a deep sleep fell on Abram. Now terror and great darkness fell on him. 13He said to Abram, “Know for sure that your offspring will live as foreigners in a land that is not theirs, and will serve them. They will afflict them four hundred years. 14I will also judge that nation, whom they will serve. Afterward they will come out with great wealth; 15but you will go to your fathers in peace. You will be buried at a good old age. 16In the fourth generation they will come here again, for the iniquity of the Amorite is not yet full.” 17It 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. 18In that day Yahweh made a covenant with Abram, saying, “I have given this land to your offspring, from the river of Egypt to the great river, the river Euphrates: 19the land of the Kenites, the Kenizzites, the Kadmonites, 20the Hittites, the Perizzites, the Rephaim, 21the Amorites, the Canaanites, the Girgashites, and the Jebusites.”
Gen 22:2 “offer him there for a burnt offering” - The sacrifice of Isaac (Gen 22:2)
Genesis 22 is known as the Akedah ("binding") account. Just as God called Abraham and gave him a mission in Gen 12:1-3, God again calls Abraham in Gen 22:1-6 to give him a mission. God's call on Abraham in Gen 12:1-3 includes the promise of future descendants if Abraham will obey God's command. In Gen 22:1-6 the command is that Abraham has to offer his son, the fulfillment of God's previous promise, as a burnt offering.
At the onset of the Akedah account, it is clearly spelled out that the motif of this command is to test Abraham. The motif of divine "test" is popular throughout the Old and New Testaments. God tested people individually and collectively. Deut 8:2 says that God tested the people of Israel multiple times during their journey to the promised land. The Tyndale Bible Dictionary defines "test" as follows: "The process of proving one’s worth. When ascribed to God in His dealings with people, it means that God tests the faith and moral character of His people" (Elwell, "Test"). By not withholding his son to safeguard his own future, Abraham proved both to God and to himself his total trust in God. The outcome of Abraham's test was much bigger than just securing his son's life. The patriarchal blessing God initially promised to Abraham in Gen 12:1-3, which was repeatedly reassured (Gen. 13:14-16; 15:4-6, 18-21; 16:10; 17:1-8, 19-21) was ensured (Gen 22:16-18).
