And I turned For he had heard the voice behind him. To see the voice; i.e., the person from whom the voice came. Seven golden candlesticks - Ἑπτα λυχνιας χρυσας· Seven golden lamps. It is absurd to say, a golden silver, or brazen candlestick. These seven lamps represented the seven Churches, in which the light of God was continually shining, and the love of God continually burning. And they are here represented as golden, to show how precious they were in the sight of God. This is a reference to the temple at Jerusalem, where there was a candlestick or chandelier of seven branches; or rather six branches; three springing out on either side, and one in the center. See Exo 25:31-37. This reference to the temple seems to intimate that the temple of Jerusalem was a type of the whole Christian Church.
