Genesis 16:4-8

And he went in to Hagar, and she conceived. And when she saw that she had conceived, she looked with contempt on her mistress. And Sarai said to Abram, “May the wrong done to me be on you! I gave my servant to your embrace, and when she saw that she had conceived, she looked on me with contempt. May the LORD judge between you and me!” But Abram said to Sarai, “Behold, your servant is in your power; do to her as you please.” Then Sarai dealt harshly with her, and she fled from her. The angel of the LORD found her by a spring of water in the wilderness, the spring on the way to Shur. And he said, “Hagar, servant of Sarai, where have you come from and where are you going?” She said, “I am fleeing from my mistress Sarai.”
