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. 23 And these three men, Shadrach, Meshach, and Abed-Nego, have fallen down in the midst of the burning fiery furnace—bound. 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.' 26 Then Nebuchadnezzar hath drawn near to the gate of the burning fiery furnace; he hath answered and said, 'Shadrach, Meshach, and Abed-Nego, servants of God Most High come forth, yea, come;' then come forth do Shadrach, Meshach, and Abed-Nego, from the midst of the fire; 27 and gathered together, the satraps, the prefects, and the governors, and the counsellors of the king, are seeing these men, that the fire hath no power over their bodies, and the hair of their head hath not been singed, and their coats have not changed, and the smell of fire hath not passed on them.

28 Nebuchadnezzar hath answered and hath said, 'Blessed 'is' the God of Shadrach, Meshach, and Abed-Nego, who hath sent His messenger, and hath delivered His servants who trusted on Him, and the word of the king changed, and gave up their bodies that they might not serve nor do obeisance to any god except to their own God. 29 And by me a decree is made, that any people, nation, and language, that doth speak erroneously concerning the God of Shadrach, Meshach, and Abed-Nego, pieces he is made, and its house is made a dunghill, because that there is no other god who is able thus to deliver.' 30 Then the king hath caused Shadrach, Meshach, and Abed-Nego, to prosper in the province of Babylon.

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.

Commentary on Daniel 3:28-30

(Read Daniel 3:28-30)

What God did for these his servants, would help to keep the Jews to their religion while in captivity, and to cure them of idolatry. The miracle brought deep convictions on Nebuchadnezzar. But no abiding change then took place in his conduct. He who preserved these pious Jews in the fiery furnace, is able to uphold us in the hour of temptation, and to keep us from falling into sin.
