Is the Book of Revelation the only place in Scripture teaching eternal torment?

Revelation 20:10 depicts hell in the following manner (NKJV, emphasis mine): > The devil, who deceived them, was cast into the lake of fire and brimstone where the beast and the false prophet are. And they will be **tormented day and night forever and ever**. Also, while it doesn't directly say the torment is eternal, Revelation 14:11 comes close as well (NKJV, emphasis mine): > And the smoke of their **torment** ascends **forever and ever**; and they have no rest day or night, who worship the beast and his image, and whoever receives the mark of his name. Aside from these two verses in Revelation, do any other Books of the Bible depict eternal torment, or is the symbolic Book of Revelation the only source for eternal torment? I'm not looking for verses that discuss eternal "punishment" (which is vaguer) or verses that speak of just "torment" without saying such is forever/eternal. Rather, I'm looking specifically for verses that depict torment/torture as being eternal/forever.
