24 Then Nebuchadnezzar the king hath been astonished, and hath risen in haste; he hath answered and said to his counsellors, 'Have we not cast three men into the midst of the fire—bound?' They have answered and are saying to the king, 'Certainly, O king.' 25 He answered and hath said, 'Lo, I am seeing four men loose, walking in the midst of the fire, and they have no hurt; and the appearance of the fourth 'is' like to a son of the gods.'

Matthew Henry's Commentary on Daniel 3:24-25

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.
