| Geneva Study Bible Where their worm dieth not, and the fire is not quenched. People's New Testament 9:48 Worm dieth not... fire is not quenched. An expression borrowed from Isa 66:24, and probably in current use among the Jews of our Savior's time, as applied to the state of future retribution. Jamieson-Fausset-Brown Bible Commentary 48. Where their worm dieth not, and the fire is not quenched-See on [1468]Mt 5:30; The "unquenchablesness" of this fire has already been brought before us (see on [1469]Mt 3:12); and the awfully vivid idea of an undying worm, everlastingly consuming an unconsumable body, is taken from the closing words of the evangelical prophet (Isa 66:24), which seem to have furnished the later Jewish Church with its current phraseology on the subject of future punishment (see Lightfoot). Matthew Henry's Concise Commentary 9:41-50 It is repeatedly said of the wicked, Their worm dieth not, as well as, The fire is never quenched. Doubtless, remorse of conscience and keen self-reflection are this never-dying worm. Surely it is beyond compare better to undergo all possible pain, hardship, and self-denial here, and to be happy for ever hereafter, than to enjoy all kinds of worldly pleasure for a season, and to be miserable for ever. Like the sacrifices, we must be salted with salt; our corrupt affections must be subdued and mortified by the Holy Spirit. Those that have the salt of grace, must show they have a living principle of grace in their hearts, which works out corrupt dispositions in the soul that would offend God, or our own consciences. |
