Genesis 22:15-19

15The angel of the LORD called to Abraham from heaven a second time 16and said, “I swear by myself, declares the LORD, that because you have done this and have not withheld your son, your only son, 17I will surely bless you and make your descendants as numerous as the stars in the sky and as the sand on the seashore. Your descendants will take possession of the cities of their enemies,

18and through your offspring Or seed all nations on earth will be blessed, Or and all nations on earth will use the name of your offspring in blessings (see 48:20) because you have obeyed me.”

19Then Abraham returned to his servants, and they set off together for Beersheba. And Abraham stayed in Beersheba.
