Exodus 2:15-17

15And sure enough, Pharaoh heard what had happened, and he tried to kill Moses. But Moses fled from Pharaoh and went to live in the land of Midian. When Moses arrived in Midian, he sat down beside a well.

16Now the priest of Midian had seven daughters who came as usual to draw water and fill the water troughs for their father’s flocks.

17But some other shepherds came and chased them away. So Moses jumped up and rescued the girls from the shepherds. Then he drew water for their flocks.
