Hebrews 11:11-12

11Abraham and his wife, Sarah, were too old to have children. But Abraham believed God's promise that they would have children. He trusted God to do what he had promised. As a result of his faith, God made it possible for him and Sarah to have a baby.

12Abraham was so old that he was almost like a dead man. But from this one man there came very many grandchildren. His family became so large that nobody could count them. They were like the number of stars in the sky. They were as many as the bits of sand on the shore of the sea.
