Amplified Bible

³⁹ from thirty years and upward even to fifty years old, everyone who entered the service to do the work in the Tent of Meeting (tabernacle); ⁴⁰ the men who were numbered by their families, by their fathers’ households, were 2,630. ⁴¹ These were numbered men of the families of the sons of Gershon, everyone who served in the Tent of Meeting (tabernacle), whom Moses and Aaron numbered just as the Lord had commanded.
