Genesis 16:4-10

So he went in to Hagar, and she conceived. And when she saw that she had conceived, her mistress became despised in her eyes. Then Sarai said to Abram, “My wrong be upon you! I gave my maid into your embrace; and when she saw that she had conceived, I became despised in her eyes. The LORD judge between you and me.” So Abram said to Sarai, “Indeed your maid is in your hand; do to her as you please.” And when Sarai dealt harshly with her, she fled from her presence. Now the Angel of the LORD found her by a spring of water in the wilderness, by the spring on the way to Shur. And He said, “Hagar, Sarai’s maid, where have you come from, and where are you going?” She said, “I am fleeing from the presence of my mistress Sarai.” The Angel of the LORD said to her, “Return to your mistress, and submit yourself under her hand.” Then the Angel of the LORD said to her, “I will multiply your descendants exceedingly, so that they shall not be counted for multitude.”
