Genesis 16:9

And the angel of the LORD found her by a fountain of water in the wilderness, by the fountain in the way to Shur.

And he said, Hagar, Sarai's maid, whence camest thou? and whither wilt thou go? And she said, I flee from the face of my mistress Sarai.

And the angel of the LORD said unto her, I will multiply thy seed exceedingly, that it shall not be numbered for multitude.

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.
