From thirty years old and older to fifty years old you will number them, all that enter in to perform the service, to do the work in the tent of meeting.
This is what belongs to the Levites: From twenty-five years old and older they will go in to do their duty concerning the service of the tent of meeting.
But they will minister with their brothers in the tent of meeting, to attend to their needs, but will not do the work. Thus you will do to the Levites concerning their duties.
