Genesis 17 – establish my covenant between me and thee and thy seed

And when Abram was ninety years old and nine, the Lord appeared to Abram, and said unto him, I am the Almighty God; walk before me, and be thou perfect. ² And I will make my covenant between me and thee, and will multiply thee exceedingly. ³ And Abram fell on his face: and God talked with him, saying, ⁴ As for me, behold, my covenant is with thee, and thou shalt be a father of many nations. ⁵ Neither shall thy name any more be called Abram, but thy name shall be Abraham; for a father of many nations have I made thee. ⁶ And I will make thee exceeding fruitful, and I will make nations of thee, and kings shall come out of thee. ⁷ And I will establish my covenant between me and thee and thy seed after thee in their generations for an everlasting covenant, to be a God unto thee, and to thy seed after thee. ⁸ And I will give unto thee, and to thy seed after thee, the land wherein thou art a stranger, all the land of Canaan, for an everlasting possession; and I will be their God. ⁹ And God said unto Abraham, Thou shalt keep my covenant therefore, thou, and thy seed after thee in their generations. ¹⁰ This is my covenant, which ye shall keep, between me and you and thy seed after thee; Every man child among you shall be circumcised.

¹⁸ And Abraham said unto God, O that Ishmael might live before thee!

²⁰ And as for Ishmael, I have heard thee: Behold, I have blessed him, and will make him fruitful, and will multiply him exceedingly; twelve princes shall he beget, and I will make him a great nation.

²⁵ And Ishmael his son was thirteen years old, when he was circumcised in the flesh of his foreskin.

²⁶ In the selfsame day was Abraham circumcised, and Ishmael his son.
