Numbers 4:9

And they shall take a cloth of blue, and cover the candlestick of the light, and his lamps ,.... Which had lamps in it, and were continually lighted, and gave light in the holy place:

and his tongs, and his snuff dishes, and all the oil vessels thereof ,

wherewith they minister unto it ; by supplying the lamps with oil, and snuffing and trimming them.
