John Trapp on Daniel 3:19

Ver. 19. And the form of his viſage was changed] Chal. the countenance of his face. Paſſionate perſons vex and diſtemper their own hearts and bodyes, Prov. 25.28. and are exceedingly disfigurged with furiouſneſs of the looks, extraordinary painting of the heart, beating of the pulſe, ſwelling of the veines, ſtammering of the tongue, gnaſhing of the teeth, as thoſe Act. 7.54. So the tyrant that martyred Laurence, ſtamped and ſtared, ramped and fared as out of his wits, ſwelling like a toad, looking like a devil, &c. See on ver. 17.

That they ſhould heat the furnace one ſeven times more] Whereas a lingring torment had been heavier, as Biſhop Ridley alſo felt it, and other Martyrs: but he ſpake as his paſſion prompted him, which oft overſhoots, Prov. 11.29.
