Deuteronomy 18:5-8
English Standard Version
6"And if a Levite comes from any of your towns out of all Israel, where he lives — and he may come when he desires — to the place that the Lord will choose,
7and ministers in the name of the Lord his God, like all his fellow Levites who stand to minister there before the Lord,
8then he may have equal portions to eat, besides what he receives from the sale of his patrimony.
