19 Then was Nebuchadnezzar full of fury, and the form of his visage was changed against Shadrach, Meshach, and Abed-nego. He spoke, and commanded that they should heat the furnace seven times more than it was wont to be heated.

Matthew Henry's Commentary on Daniel 3:19

Commentary on Daniel 3:19-27

(Read Daniel 3:19-27)

Let Nebuchadnezzar heat his furnace as hot as he can, a few minutes will finish the torment of those cast into it; but hell-fire tortures, and yet does not kill. Those who worshipped the beast and his image, have no rest, no pause, no moment free from pain, Hebrews 12:29. Could we but see into the eternal world, we should behold the persecuted believer safe from the malice of his foes, while they are exposed to the wrath of God, and tormented in unquenchable fires.
