Exodus 2:15-17 (King James Version)

 ¹⁵Now when Pharaoh heard this thing, he sought to slay Moses. But Moses fled from the face of Pharaoh, and dwelt in the land of Midian: and he sat down by a well.

 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.
