Genesis 17:21-23

Common English Bible

²¹ But I will set up my covenant with Isaac, who will be born to Sarah at this time next year.” ²² When God finished speaking to him, God ascended, leaving Abraham alone.

²³ Abraham took his son Ishmael, all those born in his household, and all those purchased with his silver—that is, every male in Abraham’s household—and he circumcised the flesh of their foreskins that same day, just as God had told him to do.
