These have power to shut heaven, that it rain not in the days of their prophecy: and have power over waters to turn them to blood, and to smite the earth with all plagues, as often as they will.

These have power to shut the heaven that no rain may fall during the days of their prophecy; and they have power over the waters to turn them into blood, and to smite the earth as often as they will with every plague.

These have authority to shut the heaven, that it may not rain rain in the days of their prophecy, and authority they have over the waters to turn them to blood, and to smite the land with every plague, as often as they may will.

They have power given to them to seal up the sky, so that no rain may fall so long as they continue to prophesy; and power over the waters to turn them into blood, and to smite the earth with various plagues whenever they choose to do so.

These have the power to keep the heaven shut, so that there may be no rain in the days when they are prophets: and they have power over the waters to make them into blood, and to send every sort of disease on the earth as their pleasure is.

These have the power to close up the heavens, so that it may not rain during the days of their prophesying. And they have power over the waters, to convert them into blood, and to strike the earth with every kind of affliction as often as they will.

These men have the power to close the heavens, so that no rain may fall during the time that they are teaching; and they have power to turn the streams into blood, and to smite the land with any curse, whenever they will.

These have power to shut heaven - That is, so far as rain is concerned - for this is immediately specified. There is probably a reference here to an ancient opinion that the rain was kept in the clouds of heaven as in reservoirs or bottles, and that when they were opened it rained; when they were closed it ceased to rain. So Job, "He bindeth up the waters in his thick clouds, and the cloud is not rent under them," Job 26:8. "Which the clouds do drop and distil upon man abundantly," Job 36:28. "Who can number the clouds in wisdom? or who can stay the bottles of heaven?" Job 38:37; compare Genesis 1:7; Genesis 7:12; Genesis 8:2; 2-Kings 7:2. To shut or close up the heavens, therefore, is to restrain the rain from descending, or to produce a drought. Compare notes on James 5:17.
That it rain not in the days of their prophecy - In the time when they prophesy. Probably the allusion here is to what is said of Elijah, 1-Kings 17:1. This would properly refer to some miraculous power; but still it may be used to denote merely that they would be clothed with the power of causing blessings to be withheld from people, as if rain were withheld; that is, that in consequence of the calamities that would be brought upon them, and the persecutions which they would endure, God would bring judgments upon people as if they were clothed with this power. The language, therefore, it seems to me, does not necessarily imply that they would have the power of working miracles.
And have power over waters to turn them to blood - The allusion here is doubtless to what occurred in Egypt, Exodus 7:17. Compare the notes on Revelation 8:8. This, too, would literally denote the power of working a miracle; but still it is not absolutely necessary to suppose that this is intended. Anything that would be represented by turning waters into blood, would correspond with all that is necessarily implied in the language. If any great calamity should occur in consequence of what was done to them that would be properly represented by turning the waters into blood so that they could not be used, and that was so connected with the treatment which they received as to appear to be a judgment of heaven on that account, or that would appear to have come upon the world in consequence of their imprecations, it would be all that is necessarily implied in this language.
And to smite the earth with all plagues - All kinds of plague or calamity; disease, pestilence, famine, flood, etc. The word "plague" - πληγῇ plēgē - which means, properly, "stroke, stripe, blow," would include any or all of these. The meaning here is, that great calamities would follow the manner in which they were treated, as if the power were lodged in their hands.
As often as they will - So that it would seem that they could exercise this power as they pleased.

These have power to shut heaven - As Elijah did, 1 Kings 17:1-18:46.
To turn them to blood - As Moses did, Exodus 7:19-25. They shall have power to afflict the land with plagues, similar to those which were inflicted on the Egyptians.

These have power to shut heaven,.... For these have the keys of the kingdom of heaven given them, and whatever they bind or loose on earth is bound or loosed in heaven; or in other words, having the true key of knowledge in matters, both of doctrine and discipline, given them, whatever they declare, according to the word of God, to be doctrines fit to be received or rejected, and to be the ordinances of God, and matters of worship to be attended to, and what are not, should be so: and in particular,
that it rain not in the days of their prophecy; that is, on their enemies, the antichristian party; for otherwise it must rain on those to whom they minister, their prophecy itself being rain in a spiritual sense: so rain is explained of prophecy in the Targum on Isaiah 5:6, which paraphrases the words thus;
"I will command the prophets that they do not prophesy upon them prophecy:''
for this is to be understood not literally, since the days of their prophecy, or preaching in sackcloth, are 1260, that is, 1260 years, and which is the term and duration of antichrist's reign: wherefore, if this was the case, there must be a famine and great distress, during this long space of time; but as this is not matter of fact, so it would not comport with that plenty, luxury, and deliciousness, in which the whore of Babylon is said to live: but the words are to be taken in a spiritual sense, and to be understood of the Gospel, and doctrines of it, or the word of God, which is sometimes compared to rain, Deuteronomy 32:2. God is the author and giver of rain, and he only; none of the vanities, or idols of the Gentiles, can give it; has the rain a father? it has, but not on earth, only God who is in heaven; and so the Gospel is of God, and it is he only that can make men able ministers of it; the rain comes down from above, from heaven, and of the same original and descent is the Gospel, it is the voice speaking from heaven; the rain falls, according to divine direction, in one place, and not another, on one city, and not another; and so the Gospel is sometimes in one place, and sometimes in another; it is forbid here, and ordered there. Showers of rain moisten and soften the earth, and make it susceptive of seed; and the Gospel is the means of softening hard hearts, and of making them capable of receiving suitable impressions: rain refreshes the earth, revives the plants and trees, and makes them fruitful; and so the Gospel, attended with a divine blessing, refreshes drooping saints, revives the work of God in them, and is the means of filling them with all the fruits of righteousness. Now the withholding of this rain denotes a famine, not of bread, or a thirst for water, but of hearing the word of the Lord; and as it is a judgment on a nation, or on a city, not to be rained upon, so it is a spiritual judgment upon a people, when God commands his clouds, his ministers, to rain no rain of the Gospel on them; and it is one of the judgments upon the antichristian party, that they have not the Gospel preached unto them, nor any dew of powerful and efficacious grace distilled on them, but are left to their blindness, darkness, and hardness of heart: and these witnesses carrying the Gospel along with them, where they prophesy and preach, is called a shutting up heaven, so that it rain not on the followers of antichrist, from whom they separate themselves, or by whom they are cast out; and this is ascribed to them, and is owing to their removal or ejection; much in the same sense as the night and darkness are to the sun's remove; that is, these follow upon it. The allusion is to the withholding of rain in the times of Elijah, one of the types of these witnesses, because of the idolatries of Ahab and Jezebel, 1-Kings 17:1. In like manner is the rain of the Gospel withheld during the reign of antichrist, because of the idolatry and superstition of the apostasy.
And have power over waters to turn them to blood; by "waters" are meant people, multitudes, nations, and tongues, and particularly those over whom antichrist reigns, Revelation 17:15, and turning of them into blood designs the confusions and wars raised among them on account of the prophesying of these witnesses, and the persecutions and bloodshed which followed upon it; which eventually are the end and issue of preaching the Gospel; see Matthew 10:34. The allusion is to one of the plagues of Egypt, and to Moses and Aaron, who were types of these witnesses turning the waters of Egypt into blood, Exodus 7:20; and answers to the second and third vials, Revelation 16:3.
And to smite the earth with all plagues as often as they will; alluding to the plagues of Egypt, one of the names of Rome, or the Roman jurisdiction, in Revelation 11:8, and which is meant by the earth here; and referring to the rest of the seven vials poured out by these witnesses, signified by seven angels; and their having power so to do as often as they will, is to be understood of these plagues being inflicted on the inhabitants of the earth, or followers of antichrist, in answer to their prophecies and prayers, which are made according to the will of God, and so always have their effect, being such.

These . . . power--Greek, "authorized power."
it rain not--Greek, "huetos brechee," "rain shower not," literally, "moisten" not (the earth).
smite . . . with all plagues--Greek, "with (literally, 'in') every plague."

These have power - And they use that power. See Revelation 11:10. To shut heaven, that it rain not in the days of their prophesying - During those "twelve hundred and sixty days." And have power over the waters - In and near Jerusalem. To turn them into blood - As Moses did those in Egypt. And to smite the earth with all plagues, as often as they will - This is not said of Moses or Elijah, or any mere man besides. And how is it possible to understand this otherwise than of two individual persons?
