Numbers 4:7, 9

“They are to spread a blue cloth over the table of the Presence and place the plates and cups on it, as well as the bowls and pitchers for the drink offering. The regular bread offering is to be on it.

“They are to take a blue cloth and cover the lampstand  used for light, with its lamps, snuffers, and firepans,  as well as its jars of oil by which they service it.
