“Then I was given a reed like a measuring rod. And the angel stood, saying, ‘Rise and measure the temple of God, the altar, and those who worship there. But leave out the court which is outside the temple, and do not measure it, for it has been given to the Gentiles. And they will tread the holy city underfoot for forty-two months.’ Revelation 11:1-2.
“Then the sixth angel sounded: And I heard a voice from the four horns of the golden altar which is before God, saying to the sixth angel who had the trumpet, ‘Release the four angels who are bound at the great river Euphrates.’” Revelation 9:13-14.
