^15-18 The angel of God spoke from Heaven a second time to Abraham: “I swear—God’s sure word!—because you have gone through with this, and have not refused to give me your son, your dear, dear son, I’ll bless you—oh, how I’ll bless you! And I’ll make sure that your children flourish—like stars in the sky! like sand on the beaches! And your descendants will defeat their enemies. All nations on Earth will find themselves blessed through your descendants because you obeyed me.”
