Genesis 16:1-6 MSG

1 Sarai, Abram's wife, hadn't yet produced a child.
2 Sarai said to Abram, "God has not seen fit to let me have a child. Sleep with my maid. Maybe I can get a family from her." Abram agreed to do what Sarai said.
3 So Sarai, Abram's wife, took her Egyptian maid Hagar and gave her to her husband Abram as a wife. Abram had been living ten years in Canaan when this took place.
4 He slept with Hagar and she got pregnant. When she learned she was pregnant, she looked down on her mistress.
5 Sarai told Abram, "It's all your fault that I'm suffering this abuse. I put my maid in bed with you and the minute she knows she's pregnant, she treats me like I'm nothing. May God decide which of us is right."
6 "You decide," said Abram. "Your maid is your business." Sarai was abusive to Hagar and she ran away.
