“And shal cast them into the furnace of fire: there shall be wailing, and gnashing of teeth.”
1611 King James Version (KJV)
Mt 13:50 Shall cast them into the furnace of fire. Here is repeated, word for word, the language of Mt 13:42,50. The tares, the chaff, the corrupt trees, the barren tree, are all represented as burned, and here also the wicked are cast into a furnace. While I suppose that the language is a figure, it can only be understood as indicating that the sufferings of Gehenna, the abode of the wicked, are intense. See Mt 8:12.
