Genesis 16:7-10

And the angel of Jehovah found her by a fountain of water in the wilderness, by the fountain in the way to Shur. And he said, Hagar, Sarai’s handmaid, whence camest thou? and whither goest thou? And she said, I am fleeing from the face of my mistress Sarai. And the angel of Jehovah said unto her, Return to thy mistress, and submit thyself under her hands. And the angel of Jehovah said unto her, I will greatly multiply thy seed, that it shall not be numbered for multitude.
