Genesis 16:4-5

16:4 He had sexual relations with Hagar, and she became pregnant. Once Hagar realized she was pregnant, she despised Sarai. 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!”
