Numbers 4:12-14

Then they shall take all the utensils of service with which they minister in the sanctuary, put them in a blue cloth, cover them with a covering of badger skins, and put them on a carrying beam. Also they shall take away the ashes from the altar, and spread a purple cloth over it. They shall put on it all its implements with which they minister there—the firepans, the forks, the shovels, the basins, and all the utensils of the altar—and they shall spread on it a covering of badger skins, and insert its poles.
