God said, “No, but Sarah your wife shall bear you a son, and you shall call his name Isaac. I will establish my covenant with him as an everlasing covenant for his descendants after him.
And I will establish my covenant between me and you and your descendants after you throughout their generations for an everlasting covenant, to be God to you and to your descendants after you.
I will multiply your descendants as the stars of heaven, and will give to your descendants all these lands; and by your descendants all the nations of the earth shall bless themselves:
and your descendants shall be like the dust of the earth, and you shall spread abroad to the west and to the east and to the north and to the south; and by you and your descendants shall all the families of the earth bless themselves.
