Genesis 16:6-10

6“Your slave is in your hands,” Abram said. “Do with her whatever you think best.” Then Sarai mistreated Hagar; so she fled from her. 7The angel of the LORD found Hagar near a spring in the desert; it was the spring that is beside the road to Shur.

8And he said, “Hagar, slave of Sarai, where have you come from, and where are you going?” “I’m running away from my mistress Sarai,” she answered. 9Then the angel of the LORD told her, “Go back to your mistress and submit to her.”

10The angel added, “I will increase your descendants so much that they will be too numerous to count.”
