Numbers 4:46-49

46All those that were numbered of the Levites, whom Moses and Aaron and the leaders of Israel numbered, after their families, and after the house of their fathers, 47From 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, 48Even those that were numbered of them, were eight thousand and five hundred and eighty. 49According to the commandment of the LORD they were numbered by the hand of Moses, every one according to his service, and according to his burden: thus were they numbered by him, as the LORD commanded Moses.
