Then they shall take a blue cloth and cover the lampstand for the light, along with its lamps, its wick cutters, its trays, and all the oil vessels, by which it is supplied;
nor does anyone light a lamp and put it under a basket, but on a lampstand, and it gives light to all who are in the house. [Mark 4:21; Luke 8:16; 11:33]
As for the mystery of the seven stars which you saw in My right hand, and the seven golden lampstands: the seven stars are the angels (divine messengers) of the seven churches, and the seven lampstands are the seven churches.
