Deuteronomy 18:5-7

Revised Standard Version Catholic Edition

⁵ For the Lord your God has chosen him out of all your tribes, to stand and minister in the name of the Lord, him and his sons for ever.

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 which the Lord will choose, ⁷ then he may minister in the name of the Lord his God, like all his fellow Levites who stand to minister there before the Lord.
