Genesis 16:10,11 (KJV)
10 And the angel of the Lord said unto her, I will multiply thy seed exceedingly, that it shall not be numbered for multitude.
11 And the angel of the Lord said unto her, Behold, thou art with child and shalt bear a son, and shalt call his name Ishmael; because the Lord hath heard thy affliction.
