Genesis 16:7 (KJV)

And Sarai said unto Abram, My wrong be upon thee: I have given my maid into thy bosom; and when she saw that she had conceived, I was despised in her eyes: the Lord judge between me and thee.

But Abram said unto Sarai, Behold, thy maid is in thy hand; do to her as it pleaseth thee. And when Sarai dealt hardly with her, she fled from her face.

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, Return to thy mistress, and submit thyself under her hands.
