This was the total of the Kohath family groups who worked at the Meeting Tent, whom Moses and Aaron counted as the Lord had commanded Moses.
These are the laws, rules, and teachings the Lord made between himself and the Israelites through Moses at Mount Sinai.
So Moses obeyed the Lord and counted them all.
The family groups of Amram, Izhar, Hebron, and Uzziel belonged to Kohath; they were the Kohathite family groups.
There were 2,750 men in the family groups.
Also, the Gershonites were counted by families and family groups,
They counted the men from thirty to fifty who were given work at the Meeting Tent and who carried the Tent.
Each man was counted as the Lord had commanded Moses; each man was given his work and told what to carry as the Lord had commanded Moses.
