Numbers 4:5

2 Take the sum of the sons of Kohath from among the sons of Levi, by their families, by their fathers` houses,

3 from thirty years old and upward even until fifty years old, all who enter on the service, to do the work in the tent of meeting.

4 This is the service of the sons of Kohath in the tent of meeting, [about] the most holy things:

5 when the camp sets forward, Aaron shall go in, and his sons, and they shall take down the veil of the screen, and cover the ark of the testimony with it,

6 and shall put thereon a covering of sealskin, and shall spread over it a cloth all of blue, and shall put in the poles of it.

7 On the table of show bread they shall spread a cloth of blue, and put thereon the dishes, and the spoons, and the bowls and the cups with which to pour out; and the continual bread shall be thereon:

8 and they shall spread on them a cloth of scarlet, and cover the same with a covering of sealskin, and shall put in the poles of it.
