'Multiply Thy Seed' in the Bible

And the Angel of Jehovah said to her, I will multiply thy seed exceedingly, that it shall not be numbered for multitude.

I will richly bless thee, and greatly multiply thy seed, as the stars of heaven, and as the sand that is on the sea-shore; and thy seed shall possess the gate of his enemies;

And I will multiply thy seed as the stars of heaven, and unto thy seed will I give all these countries; and in thy seed shall all the nations of the earth bless themselves --

And Jehovah appeared to him the same night, and said, I am the God of Abraham thy father: fear not, for I am with thee, and will bless thee, and multiply thy seed for my servant Abraham's sake.
