Genesis 16
3 Ref So after Abram had been living for ten years in the land of Canaan, Sarai took Hagar, her Egyptian servant, and gave her to Abram for his wife.
4 Ref And he went in to Hagar and she became with child, and when she saw that she was with child, she no longer had any respect for her master's wife.
5 Ref And Sarai said to Abram, May my wrong be on you: I gave you my servant for your wife and when she saw that she was with child, she no longer had any respect for me: may the Lord be judge between you and me.
6 Ref And Abram said, The woman is in your power; do with her whatever seems good to you. And Sarai was cruel to her, so that she went running away from her.
