Genesis 16:5-10

Then Sarai said to Abram, “May [the responsibility for] the wrong done to me [by the arrogant behavior of Hagar] be upon you. I gave my maid into your arms, and when she realized that she had conceived, I was despised and looked on with disrespect. May the LORD judge [who has done right] between you and me.” But Abram said to Sarai, “Look, your maid is entirely in your hands and subject to your authority; do as you please with her.” So Sarai treated her harshly and humiliated her, and Hagar fled from her. But the Angel of the LORD found her by a spring of water in the wilderness, on the road to [Egypt by way of] Shur. And He said, “Hagar, Sarai’s maid, where did you come from and where are you going?” And she said, “I am running away from my mistress Sarai.” The Angel of the LORD said to her, “Go back to your mistress, and submit humbly to her authority.” Then the Angel of the LORD said to her, “I will greatly multiply your descendants so that they will be too many to count.”
