This noun (from κολάζω) refers to the punishment or penalty imposed as correction or retribution. Jesus uses it in Matthew 25:46 in the sheep-and-goats judgment: the unrighteous 'will go away into eternal punishment' (εἰς κόλασιν αἰώνιον), while the righteous enter eternal life. First John 4:18 states that 'fear has to do with punishment' (φόβος κόλασιν ἔχει), and perfect love casts out fear because the one who fears is not perfected in love. The term can emphasize either the corrective or the retributive aspect of punishment, with context determining emphasis.
