These were the sons of Levi after the house of their fathers; even the chief of the fathers, as they were counted by number of names by their polls, that did the work for the service of the house of the LORD, from the age of twenty years and upward.
Also for the courses of the priests and the Levites, and for all the work of the service of the house of the LORD, and for all the vessels of service in the house of the LORD.
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.
From thirty years old and upward even to fifty years old, every one that came to do the service of the ministry, and the service of the burden in the tabernacle of the congregation.
