18And Abraham said to God, If only Ishmael's life might be your care!
19And God said, Not so; but Sarah, your wife, will have a son, and you will give him the name Isaac, and I will make my agreement with him for ever and with his seed after him.
20As for Ishmael, I have given ear to your prayer: truly I have given him my blessing and I will make him fertile and give him great increase; he will be the father of twelve chiefs, and I will make him a great nation.
21But my agreement will be with Isaac, to whom Sarah will give birth a year from this time.
22And having said these words, God went up from Abraham.
23And Abraham took Ishmael, his son, and all whose birth had taken place in his house, and all his servants whom he had made his for a price, every male of his house, and on that very day he gave them circumcision in the flesh of their private parts as God had said to him.
24Abraham was ninety-nine years old when he underwent circumcision.
