Numbers 4:35-37

New Living Translation

³⁵ The list included all the men between thirty and fifty years of age who were eligible for service in the Tabernacle, ³⁶ and the total number came to 2,750. ³⁷ So this was the total of all those from the Kohathite clans who were eligible to serve at the Tabernacle. Moses and Aaron listed them, just as the Lord had commanded through Moses.
