Numbers 4:48-49

The Message

^46-49 So Moses and Aaron and the leaders of Israel counted all the Levites by clan and family. All the men from thirty to fifty years of age who came to do the work of serving and carrying the Tent of Meeting numbered 8,580. At God’s command through Moses, each man was assigned his work and told what to carry.

And that’s the story of their numbering, as God commanded Moses.
