Numbers 4:4 In-Context

2 Take a census of the Kohathites separate from the other Levites, by their clans and their ancestral houses,
3 from thirty years old up to fifty years old, all who qualify to do work relating to the tent of meeting.
4 The service of the Kohathites relating to the tent of meeting concerns the most holy things.
5 When the camp is to set out, Aaron and his sons shall go in and take down the screening curtain, and cover the ark of the covenant with it;
6 then they shall put on it a covering of fine leather, and spread over that a cloth all of blue, and shall put its poles in place.
