Genesis 22:15-19

15The Angel of the Lord called to Abraham from heaven a second time

16and said, “By Myself (on the basis of Who I Am) I have sworn [an oath], declares the Lord, that since you have done this thing and have not withheld [from Me] your son, your only son [of promise],

17indeed I will greatly bless you, and I will greatly multiply your seed like the stars of the heavens and like the sand on the seashore; and your seed shall possess the gate of their enemies [by conquering them].

18Through your seed all the nations of the earth shall be blessed, because you have heard and obeyed My voice.”

19So Abraham returned to his servants, and they got up and went with him to Beersheba; and Abraham settled in Beersheba.
