These are wells without water, clouds that are carried with a tempest; to whom the mist of darkness is reserved for 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, Matthew 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.
