Deuteronomy 18:7

and ministers in the name of the Lord his God , like all his fellow Levites who stand to minister there before the Lord ,

he may minister in the name of the Lord his God like all his fellow Levites who serve there in the presence of the Lord.

Then he shall minister in the name of the Lord his God, as all his brethren the Levites do , which stand there before the Lord.
