And to the priests enrolled by genealogy according to their fathers’ house, and the Levites from twenty years old and upward, in their work by their divisions;
But the Levites shall encamp round about the tabernacle of testimony, that there be no wrath upon the congregation of the children of Israel: and the Levites shall keep the charge of the tabernacle of testimony.
From thirty years old and upward until fifty years old shall you number them; all that enter in to perform the service, to do the work in the tabernacle of meeting.
From thirty years old and upward even unto fifty years old shall you number them, every one that enters into the service, to do the work of the tabernacle of meeting.
