'Multiply Thy Seed' in the Bible

And the agent of LORD said to her, I will greatly multiply thy seed, that it shall not be numbered for multitude.

that in blessing I will bless thee, and in multiplying I will multiply thy seed as the stars of the heavens, and as the sand which is upon the seashore, and thy seed shall possess the gate of his enemies,

And I will multiply thy seed as the stars of heaven, and will give to thy seed all these lands, and in thy seed all the nations of the earth shall be blessed,

And LORD 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.
