And God said, Sarah your wife shall bear you a son indeed; and you shall call his name Isaac: and I will establish my covenant with him for an everlasting covenant, and with his descendants after him.
And I will establish my covenant between me and you and your descendants after you in their generations for an everlasting covenant, to be a God unto you, and to your descendants after you.
And I will make your descendants to multiply as the stars of heaven, and will give unto your descendants all these countries; and in your descendants shall all the nations of the earth be blessed;
And your descendants shall be as 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 in you and in your descendants shall all the families of the earth be blessed.
