⁷ I will establish my covenant between me and you and your offspring after you throughout their generations, for an everlasting covenant, to be God to you and to your offspring after you.^(A)

² Sarah conceived and bore Abraham a son in his old age, at the time of which God had spoken to him.^(A)

²⁵ The first came out red, all his body like a hairy mantle, so they named him Esau.^(A)

⁶ It is not as though the word of God has failed. For not all those descended from Israel are Israelites,^{(A) 7} and not all of Abraham’s children are his descendants, but “it is through Isaac that descendants shall be named for you.”^{(B) 8} This means that it is not the children of the flesh who are the children of God, but the children of the promise are counted as descendants.
