Genesis 16:1-6

Now Sarai, Abram’s wife, bare him no children: and she had a handmaid, an Egyptian, whose name was Hagar. And Sarai said unto Abram, Behold now, Jehovah hath restrained me from bearing; go in, I pray thee, unto my handmaid; it may be that I shall obtain children by her. And Abram hearkened to the voice of Sarai. And Sarai, Abram’s wife, took Hagar the Egyptian, her handmaid, after Abram had dwelt ten years in the land of Canaan, and gave her to Abram her husband to be his wife. And he went in unto Hagar, and she conceived: and when she saw that she had conceived, her mistress was despised in her eyes. And Sarai said unto Abram, My wrong be upon thee: I gave my handmaid into thy bosom; and when she saw that she had conceived, I was despised in her eyes: Jehovah judge between me and thee. But Abram said unto Sarai, Behold, thy maid is in thy hand; do to her that which is good in thine eyes. And Sarai dealt hardly with her, and she fled from her face.
