Exodus 2:16
Now the priest of Midian had seven daughters: and they came and drew water, and filled the troughs to water their father’s flock. Now the priest of Midian had seven daughters: and they came and drew water, and filled the troughs to water their father’s flock.
After his flight from Egypt, God directed Moses to Midian, where he found a home with Jethro. Jethro was the priest and prince of Midian, a worshiper of God. He had seven daughters who tended his flock, coming to draw water and fill the troughs to water it. Moses married one of Jethro's daughters. He remained there forty years in the service of his father-in-law as keeper of his flocks, taking over their care.
The verse introduces Moses taking up the humble work of a tender of sheep for Jethro after his training in Egypt as a mighty statesman and leader of armies, where he had not learned the lessons essential for true greatness. In keeping the flocks, watering and guarding the sheep and lambs, his sympathies were called out and he learned to care with the tenderest care for every living thing, recognizing that although sheep cannot complain of mistreatment with their voice their attitude shows it, and that God cares for all the creatures He has made. This lowly service taught what it means to be a true shepherd in place of a harsh, overbearing spirit, and by it Moses learned to be a tender shepherd for Israel.
