Matthew Henry Commentary Exodus 2:16-22

"Now the priest of Midian had seven daughters: and they came and drew water, and filled the troughs to water their father`s flock. And the shepherds came and drove them away; but Moses stood up and helped them, and watered their flock. And when they came to Reuel their father, he said, How is it that ye are come so soon to-day? And they said, An Egyptian delivered us out of the hand of the shepherds, and moreover he drew water for us, and watered the flock. And he said unto his daughters, And where is he? Why is it that ye have left the man? Call him, that he may eat bread. And Moses was content to dwell with the man: and he gave Moses Zipporah his daughter. And she bare a son, and he called his name Gershom; for he said, I have been a sojourner in a foreign land." — Exodus 2:16-22 (ASV)

Moses found shelter in Midian. He was ready to help Reuel's daughters water their flocks, even though he had been raised in learning and at court.

Moses loved to do justice and to act in defense of those he saw injured—which everyone ought to do, to the extent of their ability. He also loved to do good. Wherever God's providence places us, we should desire and try to be useful; and when we cannot do the good we would like, we must be ready to do the good we can.

Moses commended himself to the prince of Midian, who then married one of his daughters to Moses. With her, Moses had a son named Gershom, “a stranger there,” so that he might remember the land in which he had been a stranger.
