Revelation 11:3

A reed like a rod was given to me. Someone said, “Rise and measure God’s temple, and the altar, and those who worship in it.

Leave out the court which is outside of the temple, and don’t measure it, for it has been given to the nations. They will tread the holy city under foot for forty-two months.

These are the two olive trees and the two lamp stands, standing before the Lord of the earth.

If anyone desires to harm them, fire proceeds out of their mouth and devours their enemies. If anyone desires to harm them, he must be killed in this way.

These have the power to shut up the sky, that it may not rain during the days of their prophecy. They have power over the waters, to turn them into blood, and to strike the earth with every plague, as often as they desire.
