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 Isa 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, De 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, 1Ki 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, Re 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 Mt 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, Ex 7:20; and answers to the second and third vials, Re 16:3.
