The Bible of course. It is one of the other ways that gehenna was referred to. gehenna is mistranslated as "hell" as well as sheol(the grave in the OT, hades in the NT).
And the beast was taken, and with him the false prophet that wrought miracles before him, with which he deceived them that had received the mark of the beast, and them that worshipped his image. These both were cast alive into a lake of fire burning with brimstone. (Revelation 19:20, KJV)
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 for ever and ever. (Revelation 20:10, KJV)
These are the references to gehenna as the lake of fire. I'll show you the other passages(not all of em) which talk about gehenna.
