Genesis 16:5-6
16:5 Then Sarai said to Abram, “You have brought this wrong on me! I allowed my servant to have sexual relations with you, but when she realized that she was pregnant, she despised me. May the Lord judge between you and me!”
16:6 Abram said to Sarai, “Since your servant is under your authority, do to her whatever you think best.” Then Sarai treated Hagar harshly, so she ran away from Sarai.
