Genesis 17:15–27

¹⁵Then God said to Abraham, “As for Sarai your wife, you shall not call her name Sarai, but ⁷Sarah shall be her name. ¹⁶And I will bless her ^wand also give you a son by her; then I will bless her, and she shall be a mother ^xof nations; ^ykings of peoples shall be from her.”

¹⁷Then Abraham fell on his face ^zand laughed, and said in his heart, “Shall a child be born to a man who is one hundred years old? And shall Sarah, who is ninety years old, bear a child?” ¹⁸And Abraham ^asaid to God, “Oh, that Ishmael might live before You!”

¹⁹Then God said: “No, ^bSarah your wife shall bear you a son, and you shall call his name Isaac; I will establish My ^ccovenant with him for an everlasting covenant, and with his descendants after him. ²⁰And as for Ishmael, I have heard you. Behold, I have blessed him, and will make him fruitful, and ^dwill multiply him exceedingly. He shall beget ^etwelve princes, ^fand I will make him a great nation. ²¹But My ^gcovenant I will establish with Isaac, ^hwhom Sarah shall bear to you at this ⁱset time next year.” ²²Then He finished talking with him, and God went up from Abraham.

²³So Abraham took Ishmael his son, all who were born in his house and all who were bought with his money, every male among the men of Abraham’s house, and circumcised the flesh of their foreskins that very same day, as God had said to him. ²⁴Abraham was ninety-nine years old 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. ²⁶That very same day Abraham was circumcised, and his son Ishmael; ²⁷and ^jall the men of his house, born in the house or bought with money from a foreigner, were circumcised with him.
