Revelation 11:1-4

And there was given me a reed like unto a rod: and one said, Rise, and measure the temple of God, and the altar, and them that worship therein. And the court which is without the temple leave without, and measure it not; for it hath been given unto the nations: and the holy city shall they tread under foot forty and two months. And I will give unto my two witnesses, and they shall prophesy a thousand two hundred and threescore days, clothed in sackcloth. These are the two olive trees and the two candlesticks, standing before the Lord of the earth.
