God replied: Even so, your wife Sarah is to bear you a son, and you shall call him Isaac. It is with him that I will maintain my covenant as an everlasting covenant and with his descendants after him.
But God said to Abraham: Do not be distressed about the boy or about your slave woman. Obey Sarah, no matter what she asks of you; for it is through Isaac that descendants will bear your name.
Then God said: Take your son Isaac, your only one, whom you love, and go to the land of Moriah. There offer him up as a burnt offering on one of the heights that I will point out to you.
Then he gave him the covenant of circumcision, and so he became the father of Isaac, and circumcised him on the eighth day, as Isaac did Jacob, and Jacob the twelve patriarchs.
But I brought your father Abraham from the region beyond the River and led him through the entire land of Canaan. I made his descendants numerous, and gave him Isaac.
