23 Then Abraham fell on his face and rejoiced, and said in his heart, There shall a child be born unto him that is an hundred years old, and Sarah that is ninety years old shall bear.
24 And Abraham said unto God, Oh that Ishmael might live uprightly before thee!
25 And God said, Sarah thy wife shall bare thee a son, and thou shalt call his name Isaac; and I will establish my covenant with him also, for an everlasting covenant with his seed after him.
26 And as for Ishmael, I have heard thee; Behold, I have blessed him, and will make him fruitful, and will multiply him exceedingly;
27 Twelve princes shall he beget, and I will make him a great nation.
28 But my covenant will I establish with Isaac, whom Sarah shall bear unto thee at this set time in the next year.
29 And he left off talking with him; and God went up from Abraham.
30 And 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.
31 And Abraham was ninety and nine years old when he was circumcised in the flesh of his foreskin.
32 And Ishmael was thirteen years old when he was circumcised in the flesh of his foreskin.
33 In the selfsame day Abraham was circumcised, and Ishmael his son; and all the men of his house, which were born in his house, and bought with money of strangers, were also circumcised with him.
