25 He answered and said, "But I see four men unbound, walking in the midst of the fire, and they are not hurt; and the appearance of the fourth is like a son of the gods." 26 Then Nebuchadnezzar came near to the door of the burning fiery furnace; he declared, "Shadrach, Meshach, and Abednego, servants of the Most High God, come out, and come here!" Then Shadrach, Meshach, and Abednego came out from the fire. 27 And the satraps, the prefects, the governors, and the king's counselors gathered together and saw that the fire had not had any power over the bodies of those men. The hair of their heads was not singed, their cloaks were not harmed, and no smell of fire had come upon them.

28 Nebuchadnezzar answered and said, "Blessed be the God of Shadrach, Meshach, and Abednego, who has sent his angel and delivered his servants, who trusted in him, and set aside[1] the king's command, and yielded up their bodies rather than serve and worship any god except their own God. 29 Therefore I make a decree: Any people, nation, or language that speaks anything against the God of Shadrach, Meshach, and Abednego shall be torn limb from limb, and their houses laid in ruins, for there is no other god who is able to rescue in this way."

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.
