Genesis 16:4-6

4He had sexual relations with Hagar, and she became pregnant. Once Hagar realized she was pregnant, she despised Sarai.

5Then 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!”

6Abram 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.
