Numbers 4:46-49

46All those that were numbered of the Levites, whom Moses and Aaron and the princes of Israel numbered, by their families, and by their fathers’ houses, 47from thirty years old and upward even unto fifty years old, every one that entered in to do the work of service, and the work of bearing burdens in the tent of meeting, 48even those that were numbered of them, were eight thousand and five hundred and fourscore. 49According to the commandment of Jehovah they were numbered by Moses, every one according to his service, and according to his burden: thus were they numbered of him, as Jehovah commanded Moses.
