Deuteronomy 18:6-8

If a Levite moves from any town in Israel—and he is quite free to move wherever he desires—and comes to the place GOD designates for worship, he may serve there in the name of GOD along with all his brother Levites who are present and serving in the Presence of GOD. And he will get an equal share to eat, even though he has money from the sale of his parents’ possessions. * * *
