'Multiply Your Descendants' in the Bible

Then the Angel of the Lord said to her, “I will greatly multiply your descendants so that they will be too many to count.”

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

The Lord appeared to him the same night and said,“I am the God of Abraham your father;Do not be afraid, for I am with you.I will bless and favor you, and multiply your descendants,For the sake of My servant Abraham.”
