This is it that belongeth to the Levites: from twenty and five years old and upward they shall go in to wait upon the service of the tabernacle of the congregation:
Both to the genealogy of the priests by the house of their fathers, and the Levites from twenty years old and upward, in their charges, by their courses;
But the Levites shall pitch around the tabernacle of testimony; that there may 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 shalt thou number them; all that enter in to perform the service, to do the work in the tabernacle of the congregation.
From thirty years old and upward even to fifty years old shalt thou number them, every one that entereth into the service, to do the work of the tabernacle of the congregation.
Who goeth a warfare at any time at his own charges? who planteth a vineyard, and eateth not of its fruit? or who feedeth a flock, and eateth not of the milk of the flock?
