So Sarai said to Abram, "The LORD has kept me from having children. Why don't you sleep with my slave? Maybe I can build a family through her." Abram agreed with Sarai.
After Abram had lived in Canaan for ten years, Abram's wife Sarai took her Egyptian slave Hagar and gave her to her husband Abram to be his wife.
He slept with Hagar, and she became pregnant. When Hagar realized that she was pregnant, she began to be disrespectful to Sarai, her owner.
