But God said, “No, but your wife Sarah will bear you a son, and you shall name him Isaac; and I will establish My covenant with him as an everlasting covenant for his descendants after him.
But God said to Abraham, “Do not be distressed because of the boy and your slave woman; whatever Sarah tells you, listen to her, for through Isaac your descendants shall be named.
Then He said, “Take now your son, your only son, whom you love, Isaac, and go to the land of Moriah, and offer him there as a burnt offering on one of the mountains of which I will tell you.”
And He gave him the covenant of circumcision; and so Abraham fathered Isaac, and circumcised him on the eighth day; and Isaac fathered Jacob, and Jacob, the twelve patriarchs.
Then I took your father Abraham from beyond the Euphrates River and led him through all the land of Canaan, and multiplied his descendants and gave him Isaac.
