John Trapp on Isaiah 30:33

Ver. 33. For Tophet is ordained] Heb. Tophteh, which ſome derive of Pathah to entice or ſeduce, becauſe hell draweth cuſtomers; and is called alſo Infernus ab inferendo, from the great reſort that is to it. But others fetch the name from Toph a drum; becauſe thoſe idolaters who ſacrificed their children to Moloch or Saturn, in the valley of Hinnom, ſtruck up drums to drown the cries of thoſe poor tortured children. Hence it is here uſed for hell; together with that eternity of extremity which the damned there endure: and this the Aſſyrians are here threatned with, yea their very King whoſe preſervation from the ſtroke of the Angel was but a reſervation to a worſe miſchief here and hereafter: For potentes potenter torquebuntur, great men, if not good, ſhall be greatly tormented; and the more they have of the fat of the earth, the more they are ſure to fry in hell. Such therefore had need to add true grace to their high places; elſe they ſhall prove but as an high gibbet to bring them to more diſgrace in this world, and torment in the next.

Of old] Heb. from yeſterday. Hence ſome infer that hell-torments are always freſh and new; as if they had begun but yeſterday: and every ſacrifice there is ſalted with fire, Mar. 9.49. that is, it burneth but conſumeth not; fire being of a burning, but ſalt of a preſerving nature.

He hath made it deep and large] capacious enough to receive a world full of wicked ones, Pſal. 9.17.

The pile thereof is fire and much wood] Hell-fire is no Metaphorical thing, but a material, true, proper, real, and corporeal fire, Mat. 18.9. & 25.41. Luk. 16.23. for vehemency of heat, ſaith Auſtin, it exceedeth ours, as far as our fire doth exceed fire painted on the wall. That Friar ſaid too little of it, who ſaid that one might feel it burn ſeven miles of. Aetna, Veſuvius, Pietra mala, (which is a mountain in the higheſt part of the Apennines that perpetually burneth) come not near it. Some groſs Papiſts have imagined Aetna to be the place of Purgatory: Odilo Abbot of Cluniacum perſwaded Pope John the nineteenth, that he had there ſeen the tormented ſouls wailing: whereupon that Pope appointed the Feaſt of All-ſouls.

The breath of the Lord as a ſtream of brimſtone] This formidable fire then is fed with moſt tormenting temper, rivers of brimſtone: and kindled with the breath of the Almighty, throughout all eternity. Simile quiddam videmus in thermis, ubi ſulphureae ſcaturigines magno fremitu efferveſcunt: ſome reſemblance hereof we have in the hot baths, &c.
