Genesis 16:2-4

New Century Version

² Sarai said to Abram, “Look, the Lord has not allowed me to have children, so have sexual relations with my slave girl. If she has a child, maybe I can have my own family through her.”

Abram did what Sarai said. ³ It was after he had lived ten years in Canaan that Sarai gave Hagar to her husband Abram. (Hagar was her slave girl from Egypt.)

⁴ Abram had sexual relations with Hagar, and she became pregnant. When Hagar learned she was pregnant, she began to treat her mistress Sarai badly.
