Genesis 16:4-6

He went in to Hagar, and she conceived; and when she saw that she had conceived, her mistress was despised in her sight. And Sarai said to Abram, “May the wrong done me be upon you. I gave my maid into your arms, but when she saw that she had conceived, I was despised in her sight. May the LORD judge between you and me.” But Abram said to Sarai, “Behold, your maid is in your power; do to her what is good in your sight.” So Sarai treated her harshly, and she fled from her presence.
