Numbers 4:23 In-Context

21 The LORD said to Moses,
22 "Count the Gershon families. Make a list of them family by family.
23 Count all of the men who are from 30 to 50 years old. Those are the men who must come and serve at the Tent of Meeting.
24 "Here is how the Gershon families must serve. They must carry things.
25 They must carry the curtains of the holy Tent of Meeting. They must carry its covering and the outside covering of the hides of sea cows. They must carry the curtains that cover the entrance to the Tent of Meeting.
