19 Then Nebuchadnezzar was full of fury, and the expression on his face changed toward Shadrach, Meshach, and Abed-Nego. He spoke and commanded that they heat the furnace seven times more than it was usually heated. 20 And he commanded certain mighty men of valor who were in his army to bind Shadrach, Meshach, and Abed-Nego, and cast them into the burning fiery furnace. 21 Then these men were bound in their coats, their trousers, their turbans, and their other garments, and were cast into the midst of the burning fiery furnace. 22 Therefore, because the king's command was urgent, and the furnace exceedingly hot, the flame of the fire killed those men who took up Shadrach, Meshach, and Abed-Nego. 23 And these three men, Shadrach, Meshach, and Abed-Nego, fell down bound into the midst of the burning fiery furnace. 24 Then King Nebuchadnezzar was astonished; and he rose in haste and spoke, saying to his counselors, "Did we not cast three men bound into the midst of the fire?" They answered and said to the king, "True, O king." 25 "Look!" he answered, "I see four men loose, walking in the midst of the fire; and they are not hurt, and the form of the fourth is like the Son of God." 26 Then Nebuchadnezzar went near the mouth of the burning fiery furnace and spoke, saying, "Shadrach, Meshach, and Abed-Nego, servants of the Most High God, come out, and come here." Then Shadrach, Meshach, and Abed-Nego came from the midst of the fire. 27 And the satraps, administrators, governors, and the king's counselors gathered together, and they saw these men on whose bodies the fire had no power; the hair of their head was not singed nor were their garments affected, and the smell of fire was not on them.

28 Nebuchadnezzar spoke, saying, "Blessed be the God of Shadrach, Meshach, and Abed-Nego, who sent His Angel and delivered His servants who trusted in Him, and they have frustrated the king's word, and yielded their bodies, that they should not serve nor worship any god except their own God! 29 Therefore I make a decree that any people, nation, or language which speaks anything amiss against the God of Shadrach, Meshach, and Abed-Nego shall be cut in pieces, and their houses shall be made an ash heap; because there is no other God who can deliver like this." 30 Then the king promoted Shadrach, Meshach, and Abed-Nego 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.
