Genesis 16:1-4

1Now Sarai, Abram’s wife, had not borne him children. But she had an Egyptian slave-girl—her name was Hagar.

2So Sarai said to Abram, “Look now, Adonai has prevented me from having children. Go, please, to my slave-girl. Perhaps I’ll get a son by her.” Abram listened to Sarai’s voice.

3So Sarai, Abram’s wife, took her slave-girl Hagar the Egyptian—after Abram had lived ten years in the land of Canaan—and gave her to Abram her husband to be his wife.

4Then he went to Hagar and she became pregnant. When she saw that she was pregnant, in her eyes her mistress was belittled.
