Numbers 4:9-13

Then they shall take a violet cloth and cover the lampstand for the light, along with its lamps, its tongs, its trays, and all its oil containers, by which they attend to it;

and they shall put it and all its utensils in a covering of fine leather, and put it on the carrying bars.

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.
