Ark of the Covenant is shown being carried in public for all the world to see, but the Ark had to be covered when it travelled (Numbers 4:4). This will be the service of the sons of Kohath in the Tent of Meeting, about the most holy things, 5. and when the camp sets forward, Aaron and his sons will come and they will take down the covering veil and cover the Ark of Testimony with it, 6. and will put on it the covering of badgers’ skins and will spread over it a cloth wholly of blue, and will put in its poles.
