In Genesis 15:5, God told Abram, "Look toward heaven, and number the stars if you are able to number them. Then he said to him, so shall your offspring be."
Has this promise been fulfilled? Yes.
Nehemiah 9:23-24 says, "You multiplied their children as the stars of heaven, and you brought them into he land that you had told their fathers to enter and possess. So, the descendants went in and possessed the land, and you subdued before them the inhabitants of the land of the Canaanites, and gave them into their hand, with their kings and the peoples of the land, that they might do with them as they would."
