Numbers 4:7, 14

“Next they must spread a blue cloth over the table where the Bread of the Presence is displayed, and on the cloth they will place the bowls, ladles, jars, pitchers, and the special bread.

All the altar utensils—the firepans, meat forks, shovels, basins, and all the containers—must be placed on the cloth, and a covering of fine goatskin leather must be spread over them. Finally, they must put the carrying poles in place.
