Genesis 16:5-7

5And 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. 6But 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.12

7And the angel of the Lord found her by a fountain of water in the wilderness, by the fountain in the way to Shur.
