but Sarah shall her name be. 16And I will bless her, and give thee a son also of her: yea, I will bless her, and she shall be a mother of nations; kings of people shall be of her. 17Then Abraham fell upon his face, and laughed, and said in his heart, Shall a child be born unto him that is an hundred years old? and shall Sarah, that is ninety years old, bear? 18And Abraham said unto God, O that Ishmael might live before thee!

and I will establish my covenant with him for an everlasting covenant, and with his seed after him. 20And 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. 21But my covenant will I establish with Isaac, which Sarah shall bear unto thee at this set time in the next year. 22And he left off talking with him, and God went up from Abraham.

God's Rule
23And Abraham took Ishmael his son, and all that were born in his house, and all that were bought with his money, every male among the men of Abraham’s house; and circumcised the flesh of their foreskin in the selfsame day, as God had said unto him. 24And Abraham was ninety years old and nine, when he was circumcised in the flesh of his foreskin. 25And Ishmael his son was thirteen years old, when he was circumcised in the flesh of his foreskin. 26In the selfsame day was Abraham circumcised, and Ishmael his son. 27And all the men of his house, born in the house, and bought with money of the stranger, were circumcised with him.
