Numbers 4:12-14

They are to take all the serving utensils they use in the sanctuary, place them in a blue cloth, cover them with a covering made of fine leather, and put them on a carrying frame. “They are to remove the ashes from the bronze altar, spread a purple cloth over it, and place all the equipment on it that they use in serving: the firepans, meat forks, shovels, and basins — all the equipment of the altar.  They are to spread a covering made of fine leather over it and insert its poles.
