Numbers 4:8

When 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,

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

“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.

“They shall take a blue cloth and cover the lamp stand of the light, its lamps, its snuffers, its snuff dishes, and all its oil vessels, with which they minister to it.

They shall put it and all its vessels within a covering of sealskin, and shall put it on the frame.

“On the golden altar they shall spread a blue cloth, and cover it with a covering of sealskin, and shall put in its poles.
