19 Then Nebuchadnezzar hath been full of fury, and the expression of his face hath been changed concerning Shadrach, Meshach, and Abed-Nego; he answered and said to heat the furnace seven times above that which it is seen to be heated; 20 and to certain mighty men who 'are' in his force he hath said to bind Shadrach, Meshach, and Abed-Nego, to cast into the burning fiery furnace. 21 Then these men have been bound in their coats, their tunics, and their turbans, and their clothing, and have been cast into the midst of the burning fiery furnace. 22 Therefore, because that the word of the king is urgent, and the furnace heated exceedingly, those men who have taken up Shadrach, Meshach, and Abed-Nego—killed them hath the spark of the fire.

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.
