Genesis 16:1-6 NLT

1 Now Sarai, Abram’s wife, had not been able to bear children for him. But she had an Egyptian servant named Hagar.
2 So Sarai said to Abram, “The has prevented me from having children. Go and sleep with my servant. Perhaps I can have children through her.” And Abram agreed with Sarai’s proposal.
3 So Sarai, Abram’s wife, took Hagar the Egyptian servant and gave her to Abram as a wife. (This happened ten years after Abram had settled in the land of Canaan.)
4 So Abram had sexual relations with Hagar, and she became pregnant. But when Hagar knew she was pregnant, she began to treat her mistress, Sarai, with contempt.
5 Then Sarai said to Abram, “This is all your fault! I put my servant into your arms, but now that she’s pregnant she treats me with contempt. The will show who’s wrong—you or me!”
6 Abram replied, “Look, she is your servant, so deal with her as you see fit.” Then Sarai treated Hagar so harshly that she finally ran away.
