Revelation 11:1-6

Then there was given to me a measuring rod like a staff; and someone said, “Rise and measure the temple of God and the altar [of incense], and [count] those who worship in it. [Ezek 40-42] But leave out the court [of the Gentiles] which is outside the temple and do not measure it, because it has been given to the Gentiles (the nations); and they will trample the holy city for forty-two months (three and one-half years). [Dan 8:9-14; Zech 12:3; Luke 21:24] And I will grant authority to My two witnesses, and they will prophesy for twelve hundred and sixty days (forty-two months; three and one-half years), dressed in sackcloth.” [Deut 18:18; Mal 4:5; Mark 9:4] These [witnesses] are the two olive trees and the two lampstands which stand before the Lord of the earth. [Zech 4:3, 11-14] And if anyone wants to harm them, fire comes out of their mouth and devours their enemies; so if anyone wants to harm them, he must be killed in this way. [2 Kin 1:10-12; Jer 5:14] These [two witnesses] have the power [from God] to shut up the sky, so that no rain will fall during the days of their prophesying [regarding judgment and salvation]; and they have power over the waters (seas, rivers) to turn them into blood, and to strike the earth with every [kind of] plague, as often as they wish. [Ex 7:14-19; 1 Kin 17:1]
