Numbers 4:11-15

Over the golden altar they shall spread a violet cloth, and cover it with a covering of fine leather, and they shall insert its carrying poles;

and they shall take all the utensils of service, with which they serve in the sanctuary, and put them in a violet cloth and cover them with a covering of fine leather, and put them on the carrying bars.

Then they shall clean away the ashes from the altar, and spread a purple cloth over it.

They shall also put on it all its utensils by which they serve in connection with it: the firepans, the forks, shovels, and the basins, all the utensils of the altar; and they shall spread a cover of fine leather over it and insert its carrying poles.

When Aaron and his sons have finished covering the holy objects and all the furnishings of the sanctuary, when the camp is to set out, after that the sons of Kohath shall come to carry them by the poles, so that they will not touch the holy objects and die. These are the things in the tent of meeting that the sons of Kohath are to carry.
