Numbers 4:14-15
And they shall put on it all the utensils of the altar, which are used for the service there, the fire pans, the forks, the shovels, and the basins, all the utensils of the altar; and they shall spread on it a covering of goatskin, and shall put in its poles.And when Aaron and his sons have finished covering the sanctuary and all the furnishings of the sanctuary, as the camp sets out, after that the sons of Kohath shall come to carry these, but they must not touch the holy things, lest they die. These are the things of the tent of meeting that the sons of Kohath are to carry.
