2Pet 2:17

“These are wells without water,.... Which look large and deep, promise much, and have nothing in them; so these men looked like angels of light, transformed themselves as ministers of righteousness, had a form of godliness, and boasted of their great knowledge; promised great advantages to their followers, but were like deceitful brooks, or dry wells, and so disappointed those that came to them, and attended on them; having nothing but the filth and slime of error and iniquity, being destitute both of the grace of God, comparable to water, and of the truth of heavenly doctrine, which is like the rain that fills the wells, pools, and fountains. Clouds that are carried with a tempest; these false teachers may be compared to clouds for their number, for many antichrists and false prophets soon came into the world; and for their sudden rise in the churches, into which they crept privily and unawares; and because of the general darkness they spread, for when errors and heresies prevail it is a dark and cloudy day with the churches, a day of gloominess and darkness, of thick darkness, a day of trouble, rebuke, and blasphemy; and because of the height of them, especially light clouds, as these are compared to, who are high in their own conceits and imaginations, and think, and give out themselves to be some great persons; and also because of their sudden destruction, which lingers and slumbers not, but comes upon them in a moment, and their glory passes away like the morning cloud: and these may be said to be as clouds "carried with a tempest": of their own lusts and passions, by which they are governed, and are led, and carried away with the force of them, and have no power to resist them, being under the dominion of them, and captives to them; and of Satan's temptations, who works effectually in them, with all power, signs, and lying wonders, and with all deceivableness of unrighteousness, and being taken in his snare, are led captive by him at his will: Jude says, "carried about of winds", Jde 1:12, with every wind of false doctrine, like meteors in the air; are never at a point, always unsteady and unsettled, and ready to embrace every new and upstart notion: to whom the mist of darkness is reserved for ever; the nature of their punishment is expressed by "darkness", the blackest darkness, the mist of darkness, and which Jude calls blackness of darkness, the same with utter darkness; and which signifies a most forlorn and uncomfortable condition, and is a righteous judgment, and just retaliation upon them who studied to darken counsel by words without knowledge; and the certainty of their punishment is signified by its being "reserved", even as the happiness of the saints, and the safety and sureness of it are represented by an inheritance reserved in heaven: and as God has his treasures, magazines, and stores of grace and mercy, felicity and glory, for his people; so he has his wrath and vengeance reserved, laid up in store with him, and sealed up among his treasures, which he will surely bring forth in his own time: and the duration of this punishment is "for ever"; it is a worm that never dies, a fire that is never quenched, Isa 66:24 Mar 9:44; it is everlasting fire and burnings, the smoke of which ascends for ever and ever.”

“These are wells without water - Persons who, by their profession, should furnish the water of life to souls athirst for salvation; but they have not this water; they are teachers without ability to instruct; they are sowers, and have no seed in their basket. Nothing is more cheering in the deserts of the east than to meet with a well of water; and nothing more distressing, when parched with thirst, than to meet with a well that contains no water. Clouds that are carried with a tempest - In a time of great drought, to see clouds beginning to cover the face of the heavens raises the expectation of rain; but to see these carried off by a sudden tempest is a dreary disappointment. These false teachers were equally as unprofitable as the empty well, or the light, dissipated cloud. To whom the mist of darkness is reserved - That is, an eternal separation from the presence of God, and the glory of his power. They shall be thrust into outer darkness, Mat 8:12; into the utmost degrees of misery and despair. False and corrupt teachers will be sent into the lowest hell; and be "the most downcast, underfoot vassals of perdition." It is scarcely necessary to notice a various reading here, which, though very different in sound, is nearly the same in sense. Instead of νεφελαι, clouds, which is the common reading, και ὁμιχλαι, and mists, or perhaps more properly thick darkness, from ὁμου, together, and αχλυς, darkness, is the reading in ABC, sixteen others, Erpen's Arabic, later Syriac, Coptic, Ethiopic, and Vulgate, and several of the fathers. This reading Griesbach has admitted into the text.”

“(Jde 1:12-13.) wells--"clouds" in Jude; both promising (compare Pe2 2:19) water, but yielding none; so their "great swelling words" are found on trial to be but "vanity" (Pe2 2:18). clouds--The oldest manuscripts and versions read, "mists," dark, and not transparent and bright as "clouds" often are, whence the latter term is applied sometimes to the saints; fit emblem of the children of darkness. "Clouds" is a transcriber's correction from Jde 1:12, where it is appropriate, "clouds . . . without water" (promising what they do not perform); but not here, "mists driven along by a tempest." mist--blackness; "the chilling horror accompanying darkness" [BENGEL].”
