The mystery of the seven stars which thou sawest in my right hand, and the seven golden candlesticks. The seven stars are the angels of the seven churches: and the seven candlesticks which thou sawest are the seven churches.
Berean Study Bible (BSB) - Revelation 1:20 >This is the mystery of the seven stars you saw in My right hand and of the seven golden lampstands: The seven stars are the angels of the seven churches, and the seven lampstands are the seven churches.
