“And He said, “Do not lay your hand on the lad, or do anything to him; for now I know that you fear God, since you have not withheld your son, your only son, from Me.” ………..and said: “By Myself I have sworn, says the Lord, because you have done this thing, and have not withheld your son, your only son— blessing I will bless you, and multiplying I will multiply your descendants as the stars of the heaven and as the sand which is on the seashore; and your descendants shall possess the gate of their enemies. In your seed all the nations of the earth shall be blessed, because you have obeyed My voice.””
Genesis 22:12, 16-18 NKJV
