Numbers 4:36

34 So Moses, Aaron, and the leaders of the congregation numbered the Kohathites by their clans and families,

35 everyone from thirty to fifty years old who came to serve in the work at the Tent of Meeting.

And those numbered by their clans totaled 2,750.

37 These were counted from the Kohathite clans, everyone who could serve at the Tent of Meeting. Moses and Aaron numbered them according to the command of the LORD through Moses.

38 Then the Gershonites were numbered by their clans and families,

This was said to Israel at a particular time, so it is wise to read it together with the surrounding text. Do read the surrounding verses too, because the context often says more than a single verse.
