And he opened the bottomless pit; and there arose a smoke out of the pit, as the smoke of a great furnace; and the sun and the air were darkened by reason of the smoke of the pit.

And he opened the pit of the abyss; and there went up a smoke out of the pit, as the smoke of a great furnace; and the sun and the air were darkened by reason of the smoke of the pit.

And he opened the bottomless pit: and the smoke of the pit arose, as the smoke of a great furnace; and the sun and the air were darkened with the smoke of the pit.

And it opened the pit of the abyss; and there went up smoke out of the pit as the smoke of a great furnace; and the sun and the air were darkened with the smoke of the pit.

and he did open the pit of the abyss, and there came up a smoke out of the pit as smoke of a great furnace, and darkened was the sun and the air, from the smoke of the pit.

and he opened the depths of the bottomless pit. And smoke came up out of the pit resembling the smoke of a vast furnace, so that the sun was darkened, and the air also, by reason of the smoke of the pit.

And he made the great deep open and a smoke went up from it, like the smoke of a great oven; and the sun and the air were made dark because of the smoke.

He opened the shaft of the bottomless pit, and smoke went up out of the shaft, like the smoke from a great furnace. The sun and the air were darkened because of the smoke from the pit.

And he opened the well of the abyss. And the smoke of the well ascended, like the smoke of a great furnace. And the sun and the air were obscured by the smoke of the well.

He opened the bottomless pit, and from the pit rose a smoke like the smoke of a great furnace. The sun and the air grew dark because of the smoke from the pit.

And he opened the bottomless pit - It is represented before as wholly confined, so that not even the smoke or vapor could escape.
And there arose a smoke out of the pit - Compare Revelation 14:11. The meaning here is that the pit, as a place of punishment, or as the abode of the wicked, was filled with burning sulphur, and consequently that it emitted smoke and vapor as soon as opened. The common image of the place of punishment, in the Scriptures, is that of a "lake that burns with fire and brimstone." Compare Revelation 14:10; Revelation 19:20; Revelation 20:10; Revelation 21:8. See also Psalm 11:6; Isaiah 30:33; Ezekiel 38:22. It is not improbable that this image was taken from the destruction of Sodom and Gomorrah, Genesis 19:24. Such burning sulphur would produce, of course, a dense smoke or vapor; and the idea here is, that the pit had been closed, and that as soon as the door was opened a dense column escaped that darkened the heavens. The purpose of this is, probably, to indicate the origin of the plague that was about to come upon the world. It would be of such a character that it would appear as if it had been emitted from hell; as if the inmates of that dark world had broke loose upon the earth. Compare notes on Revelation 6:8.
As the smoke of a great furnace - So in Genesis 19:28, whence probably this image is taken: "And he looked toward Sodom and Gomorrah, and all the land of the plain, and beheld and lo, the smoke of the country went up as the smoke of a furnace."
And the sun and the air were darkened, - As will be the case when a smoke ascends from a furnace. The meaning here is, that an effect would be produced as if a dense and dark vapor should ascend from the under-world. We are not, of course, to understand this literally.

He opened the bottomless pit - Το φρεαρ της αβυσσου· The pit of the bottomless deep. Some think the angel means Satan, and the bottomless pit hell. Some suppose Mohammed is meant; and Signior Pastorini professes to believe that Luther is intended!
There arose a smoke - False doctrine, obscuring the true light of heaven.

(4) And he opened the bottomless pit; and there arose a smoke out of the pit, as the smoke of a great furnace; and the sun and the air were darkened by reason of the smoke of the pit.
(4) To this is added, the smoke of the hellish and infernal dark spirits, darkening all things in heaven and in earth. The spiritual darkness is the cause of all disorder and confusion: For the devil at a certain time sent these spirits into his kingdom, that he might at once and with one action overthrow all things and pervert if it were possible the elect themselves. By this darkness, all spiritual light, both active as of the sun and passive as of the air which is lightened by the sun, is taken away: and this is that which goes before the spirits: it follows of the spirits themselves.

And he opened the bottomless pit,.... With the key that was given him; he made use of his universal power over all bishops and churches, enacted laws, issued out decrees, made articles of faith, and imposed them on men's consciences, and obliged all to submit to his hellish principles and practices; and this, as it may be applied to Mahomet, the eastern antichrist, may regard the publishing of his Alcoran, and obliging all his followers to receive it as the infallible word of God:
and there arose a smoke out of the pit, as the smoke of a great furnace; the Complutensian edition reads, "of a burning furnace"; and so the Syriac and Arabic versions; which may design false doctrine, and superstitious worship, which sprung from the decrees of popes and councils, and the Alcoran of Mahomet: and smoke being a dark thin vapour, and very troublesome to the eyes and nose, and of a perishing nature, which soon vanishes away, these are fitly expressed by it; for they are the hidden things of darkness, and the authors and abettors of them are such who darken counsel by words without knowledge; they are empty things, have no solidity and substance in them, are comparable to wood, hay, stubble, smoke, and wind; and are very troublesome and offensive to all enlightened persons, and who have the smell and savour of divine things; and will all perish with the using, being the doctrines and commandments of men, when the true Gospel is an everlasting one. Smoke sometimes designs great afflictions, punishments, and judgments upon men, Genesis 15:17; and here may represent those judgments, both spiritual and temporal, which the antichristian doctrine and worship, brought upon the world, and which have been manifest in all ages since.
And the sun and the air were darkened by reason of the smoke of the pit; Christ, the sun of righteousness, was greatly obscured by the Romish antichrist, by his false doctrine and worship, in his offices, merits, and grace, he taking upon him to be head of the church, the infallible interpreter of Scripture, and to give out pardons and indulgences; and particularly by the doctrines of merit, of works of supererogation, and of justification by works, &c. as he also was by Mahomet, who represented him only as a mere man, and exalted himself above him as a prophet; and by both were "the air", the church which receives its light from Christ, darkened; or the Scriptures, which are the breath of God, are given by inspiration of him, these were most grievously beclouded, and most wretchedly perverted, both by the decrees of popes, and the Alcoran of Mahomet. And it is remarkable what Abulpharagius (b), an Arabic writer, reports, that in the seventeenth year of Heraclius the emperor, which was the year 627, and the fifth of the Hegira, in which year Mahomet began to plunder and make war; for in this year was his plundering excursion into Dumato'l Jundal, and the battle of Bani Lahyan, that half of the body of the sun was darkened; and the darkness remained from Tisrin the first, to the month Haziran, so that very little of its light appeared; which might portend that darkness he was introducing by his wretched religion. And frequently the sun and air have been darkened at noonday by the locusts, as Pliny (c) relates; and of which we have had a late account from Transylvania; see Exodus 8:15.
(b) Hist. Dynast. p. 99, 102. (c) Nat. Hist. l. 11. c. 29.

And there arose a smoke out of the pit - The locusts, who afterwards rise out of it, seem to be, as we shall afterwards see, the Persians; agreeable to which, this smoke is their detestable idolatrous doctrine, and false zeal for it, which now broke out in an uncommon paroxysm. As the smoke of a great furnace - where the clouds of it rise thicker and thicker, spread far and wide, and press one upon another, so that the darkness increases continually. And the sun and the air were darkened - A figurative expression, denoting heavy affliction. This smoke occasioned more and more such darkness over the Jews in Persia.
