20. And as for Ishmael, I have heard thee: Behold, I shall bless him and will make him fruitful and will multiply him exceedingly; he shall beget twelve princes, and I will make him a great nation.
21. But I will establish my covenant with Isaac, whom Sarah shall bear unto thee at this set time in the next year.

24. And Abraham was ninety-nine years old when he was circumcised in the flesh of his foreskin.
25. And Ishmael his son was thirteen years old when he was circumcised in the flesh of his foreskin.
26. In that same day Abraham was circumcised and Ishmael his son.
27. And all the men of his house, born in the house and bought with money from strangers, were circumcised with him.
