Genesis 16:4-6

New Catholic Bible

But once she realized that she was pregnant, she no longer treated her mistress with respect. ⁵ Therefore, Sarai said to Abram, “May this affront fall upon you! I gave you my maid to embrace, but when she realized that she was pregnant, she stopped treating me with respect. Let the Lord judge between you and me.”

⁶ Abram said to Sarai, “Behold, your slave is in your hands. Do with her as you see fit.” Sarai then maltreated her so much that Hagar ran away.
