Numbers 4:46-49

46All who were numbered of the Levites, whom Moses, Aaron, and the leaders of Israel numbered, by their families and by their fathers’ houses,

47from thirty years old and above, even to fifty years old, everyone who came to do the work of service and the work of bearing burdens in the tabernacle of meeting—

48those who were numbered were eight thousand five hundred and eighty.

49According to the commandment of the Lord they were numbered by the hand of Moses, each according to his service and according to his task; thus were they numbered by him, as the Lord commanded Moses.
