This is it that belongs to the Levites: from twenty and five years old and upward they shall go in to wait on 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 round about the tabernacle of testimony, that there be no wrath on 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 the congregation.
From thirty years old and upward even to fifty years old shall you number them, every one that enters into the service, to do the work of the tabernacle of the congregation.
Who goes a warfare any time at his own charges? who plants a vineyard, and eats not of the fruit thereof? or who feeds a flock, and eats not of the milk of the flock?
