Fittingly, the two witnesses are now seen to perform signs reminiscent of those of Moses and Elijah. For example, John says of them: “And if anyone wants to harm them, fire issues forth from their mouths and devours their enemies; and if anyone should want to harm them, in this manner he must be killed. These have the authority to shut up heaven that no rain should fall during the days of their prophesying.”​—Revelation 11:5, 6a.

17. (a) What events in the days of Elijah involved a drought and fire? (b) How did fire issue forth from the mouths of the two witnesses, and what drought was involved?

¹⁷ What of Elijah? In the days of the kings of Israel, this prophet proclaimed a drought as an expression of Jehovah’s indignation on the Baal-worshipping Israelites. It lasted three and a half years. (1 Kings 17:1; 18:41-45; Luke 4:25; James 5:17) Later, when unfaithful King Ahaziah sent soldiers to force Elijah to come into his royal presence, the prophet called down fire from heaven to consume the soldiers. Only when a military commander showed proper respect for his position as a prophet did Elijah consent to accompany him to the king. (2 Kings 1:5-16) Likewise, between 1914 and 1918, the anointed remnant boldly drew attention to the spiritual drought in Christendom and warned of fiery judgment at “the coming of the great and fear-inspiring day of Jehovah.”​—Malachi 4:1, 5; Amos 8:11.

18. (a) What authority is given the two witnesses, and how was this similar to that given Moses? (b) How did the two witnesses expose Christendom?

¹⁸ John goes on to say of the two witnesses: “And they have authority over the waters to turn them into blood and to strike the earth with every sort of plague as often as they wish.” (Revelation 11:6b) In order to persuade Pharaoh to let Israel go free, Jehovah used Moses in striking oppressive Egypt with plagues, including the turning of water into blood. Centuries later, the Philistine enemies of Israel well remembered Jehovah’s acts against Egypt, causing them to cry: “Who will save us from the hand of this majestic God? This is the God that was the smiter of Egypt with every sort of slaughter [“plague,” Revised Standard Version] in the wilderness.” (1 Samuel 4:8; Psalm 105:29) Moses portrayed Jesus, who had authority to pronounce God’s judgments on the religious leaders of his day. (Matthew 23:13; 28:18; Acts 3:22) And during the first world war Christ’s brothers, the two witnesses, exposed the death-dealing quality of “the waters” that Christendom was serving to her flocks.
