I was in the Spirit on the Lord's day, and heard a great voice behind me, as of a trumpet,

And one of the elders answered, saying to me, As for those who are clothed with white apparel, who are they, and whence do they come?

And there was given to me a reed like a measuring rod, saying, Arise, and measure the temple of God, and the altar, and those who worship at it;

And he showed me a river of water of life, clear as crystal, issuing out of the throne of God, and of the Lamb.
