Genesis 17:19
19 God said, “No, Sarah your wife is going to bear you a son, and you will name him Isaac. ▼▼ Heb “will call his name Isaac.” The name means “he laughs,” or perhaps “may he laugh” (see the note on the word “laughed” in v.
17).
I will confirm my covenant with him as a perpetual ▼ covenant for his descendants after him.
