Deuteronomy 18:6-8

6“Now if a Levite comes from any of your 1towns throughout Israel where he 2resides, and he comes 3whenever he desires to the place which the Lord chooses, 7then he shall serve in the name of the Lord his God, like all his fellow Levites who stand there before the Lord. 84They shall eat 5equal portions, except for what they receive from the sale of their fathers’ estates.
