Numbers 4:6-9, 11-12

Then they shall put on it a covering of goatskin and spread on top of that a cloth all of blue, and shall put in its poles. And over the table of the bread of the Presence they shall spread a cloth of blue and put on it the plates, the dishes for incense, the bowls, and the flagons for the drink offering; the regular showbread also shall be on it. Then they shall spread over them a cloth of scarlet and cover the same with a covering of goatskin, and shall put in its poles. And they shall take a cloth of blue and cover the lampstand for the light, with its lamps, its tongs, its trays, and all the vessels for oil with which it is supplied.

And over the golden altar they shall spread a cloth of blue and cover it with a covering of goatskin, and shall put in its poles. And they shall take all the vessels of the service that are used in the sanctuary and put them in a cloth of blue and cover them with a covering of goatskin and put them on the carrying frame.
