In Isa. 34:9, 10, the prophet, speaking of the land of Idumea, says: “And the streams thereof shall be turned into pitch, and the dust thereof into brimstone, and the land thereof shall become burning pitch. It shall not be quenched night nor day: the smoke thereof shall go up forever: from generation to generation it shall lie waste; none shall pass through it forever and ever.” But two applications can be made of this language. Either it refers to the literal land of Edom east and south of Judea, or it is a figure to represent the whole world in the day of final conflagration. In either case it is equally to the point. If the literal land of Idumea is meant, and the language has reference to the desolations which have fallen upon it, then certainly no eternity of duration is implied in the declaration that the smoke thereof shall go up forever. For all the predictions against the land of Idumea have long since been fulfilled, and the judgments have ceased. If it refers to the fires of the last day, when the elements melt with fervent heat, no eternity of duration is even then implied in the expression; for the earth is not to be forever destroyed by the purifying fires of the last day. It is to rise from its ashes, and a new earth come forth purified from all the stains of sin, and free from all the deformity of the curse, to be the everlasting abode of the righteous. Here is an instance in which the word, forever, apply it in either of the only two ways possible, must denote a limited period. And here the Septuagint uses αἰων (_aion_) the same as is used in Rev. 14:11; and from this passage in Isaiah, the language in Revelation was probably borrowed. That the words αἰων and αἰωνιος sometimes denote a limited period, and not invariably one of eternal duration, will appear in the examination of the only remaining text that calls for consideration, namely, Rev. 20:10: “And the devil that deceived them was cast into the lake of fire and brimstone, where the beast and the false prophet are, and shall be tormented day and night forever and ever.” The same limitation is apparent in this text that was observed in the preceding. It does not refer to all the wicked, but speaks only of the devil, the beast, and the false prophet. The lake of fire, the place and means of their torment, is again mentioned in verse 14; but there it is the symbol of complete and utter destruction. Death and Hades, it says, were cast into the lake of fire, and after this it is said, “There shall be no more death.” Rev. 21:4. Whatever, then, is cast into the lake of fire, after it has wrought its work of destruction upon them, no longer exists. This is the plain inference from what is here asserted respecting death. Then follows the testimony of verse 15, that “whosoever was not found written in the book of life, was cast into the lake of fire.” And this makes a final disposition of all who are not saved in the kingdom of Heaven.
