Numbers 4:46-49

All who were numbered of the Levites, whom Moses, Aaron, and the leaders of Israel numbered, by their families and by their fathers’ houses, from 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— those who were numbered were eight thousand five hundred and eighty. According 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.
