“And YHWH has looked after Sarah as He has said, and YHWH does to Sarah as He has spoken;”— Genesis 21:1 (LSV)
1And YHWH has looked after Sarah as He has said, and YHWH does to Sarah as He has spoken;
2and Sarah conceives, and bears a son to Abraham, to his old age, at the appointed time that God has spoken of with him;
3and Abraham calls the name of his son who is born to him, whom Sarah has borne to him—Isaac;
4and Abraham circumcises his son Isaac, [being] a son of eight days, as God has commanded him.
