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. 17And the shepherds came and drove them away; but Moses stood up and helped them, and watered their flock. 18And when they came to Reuel their father, he said, How is it that ye are come so soon to-day? 19And they said, An Egyptian delivered us out of the hand of the shepherds, and moreover he drew water for us, and watered the flock.
