Exodus 2:16-19

16Now the priest of Midian had seven daughters, and they came and drew water and filled the troughs to water their father's flock.

17The shepherds came and drove them away, but Moses stood up and saved them, and watered their flock.

18When they came home to their father Reuel, he said, "How is it that you have come home so soon today?"

19They said, "An Egyptian delivered us out of the hand of the shepherds and even drew water for us and watered the flock."
