Numbers 4:5–6

When the camp is to move, Aaron and his sons are to go in and take down the shielding curtain and put it over the ark of the covenant law. Then they are to cover the curtain with a durable leather, spread a cloth of solid blue over that and put the poles in place.

Whenever the camp is about to move on, Aaron and his sons are to go in, take down the screening curtain, and cover the ark of the testimony with it. They are to place over this a covering made of fine leather, spread a solid blue cloth on top, and insert its poles.

When the camp moves, Aaron and his sons must enter the Tabernacle first to take down the inner curtain and cover the Ark of the Covenant with it. Then they must cover the inner curtain with fine goatskin leather and spread over that a single piece of blue cloth. Finally, they must put the carrying poles of the Ark in place.

When setting out the camp, Aaron and his sons will go and lower the curtain of the covering and cover with it the ark of the testimony. They will put on it a covering of fine leather, and they will spread a cloth of perfect blue over it, and they will place its poles.

And when the camp setteth forward, Aaron shall come, and his sons, and they shall take down the covering vail, and cover the ark of testimony with it: And shall put thereon the covering of badgers’ skins, and shall spread over it a cloth wholly of blue, and shall put in the staves thereof.
