Genesis 22:16-18

16and said, “‘I solemnly swear by my own name,’ decrees the Lord, ‘that because you have done this and have not withheld your son, your only son,

17I will indeed bless you, and I will greatly multiply your descendants so that they will be as countless as the stars in the sky or the grains of sand on the seashore. Your descendants will take possession of the strongholds of their enemies.

18Because you have obeyed me, all the nations of the earth will pronounce blessings on one another using the name of your descendants.’”
