Genesis 22:15-19 - The Lord's Seventh Promise To Abraham
15 The angel of the LORD called to Abraham a second time from heaven 16 and said, "I have taken an oath to swear by myself," declares the LORD, "that since you have carried this out and have not withheld your only unique son, 17 I will certainly bless you and make your descendants as numerous as the stars in heaven and as the sand on the seashore. Your descendants will take possession of the gates of their enemies. 18 Furthermore, through your descendants all the nations of the earth will be blessed, because you have obeyed my command."
19 After this, Abraham returned to his servants and they set out together for Beer-sheba, where Abraham settled.
