Numbers 4:6

4“This is the service of the sons of Kohath in the Tent of Meeting, regarding the most holy things.

5When the camp moves forward, Aaron shall go in with his sons; and they shall take down the veil of the screen, cover the ark of the Testimony with it,

6put a covering of sealskin on it, spread a blue cloth over it, and put in its poles.

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

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