Genesis 16:4-6

4Abram had sex with Hagar and she became pregnant. When Hagar knew that she was pregnant, she no longer respected Sarai.

5Then Sarai said to Abram, ‘It is because of you that Hagar is now insulting me. I gave her to you so that you could have sex with her. Now she is pregnant and she does not respect me. The Lord will decide who is right, you or me.’

6Abram said to Sarai, ‘Hagar is your servant and you have authority over her. Do to her whatever you think is right.’ Then Sarai caused trouble for Hagar. So Hagar ran away from Sarai.
