Genesis 16:1-3 NIV

[1] Now Sarai, Abram’s wife, had borne him no children. But she had an Egyptian slave named Hagar; [2] so she said to Abram, “The LORD has kept me from having children. Go, sleep with my slave; perhaps I can build a family through her.” Abram agreed to what Sarai said. [3] So after Abram had been living in Canaan ten years, Sarai his wife took her Egyptian slave Hagar and gave her to her husband to be his wife.
