Therefore because the king's commandment was urgent, and the furnace exceeding hot, the flame of the fire slew those men that took up Shadrach, Meshach, and Abed-nego.

For the king's commandment was urgent, and the furnace was heated exceedingly. And the flame of the fire slew those men that had cast in Sidrach, Misach, and Abdenago.

Forasmuch as the king's commandment was rigorous, and the furnace exceeding hot, the flame of the fire slew those men that had taken up Shadrach, Meshach, and Abed-nego.

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.

Therefore because the king's commandment was urgent, and the furnace exceeding hot, the flames of the fire slew those men that took up Shadrach, Meshach, and Abednego.

And because the king's order was not to be put on one side, and the heat of the fire was so great, the men who took up Shadrach, Meshach, and Abed-nego were burned to death by the flame of the fire.

Therefore because the king's commandment was peremptory, and the furnace exceeding hot, the flame of the fire slew those men that took up Shadrach, Meshach, and Abed-nego.

Propterea quod urgebat, vel, festinabat, ud verbum praeceptum regis, et fornacem vehementer jusserat accendi, viros illos qui extulerant Sadrach, Mesach, et Abed-nego occidit t kavilla, alii vertunt fammam, ignis.

Therefore, because the king's commandment was urgent - Margin, as in Chaldee, "word." The meaning is, that the king would admit of no delay; he urged on the execution of his will, even at the imminent peril of those who were entrusted with the execution of his command.
And the furnace exceeding hot - Probably so as to send out the flame so far as to render the approach to it dangerous. The urgency of the king would not admit of any arrangements, even if there could have been any, by which the approach to it would be safe.
The flame of the fire slew those men - Margin, as in Chaldee, "spark." The meaning is, what the fire threw out - the blaze, the heat. Nothing can be more probable than this. It was necessary to approach to the very mouth of the furnace in order to cast them in, and it is very conceivable that a heated furnace would belch forth such flames, or throw out such an amount of heat, that this could not be done but at the peril of life. The Chaldee word rendered "slew" here, means "killed." It does not mean merely that they were overcome with the heat, but that they actually died. To expose these men thus to death was an act of great cruelty, but we are to remember how absolute is the character of an Oriental despot, and how much enraged this king was, and how regardless such a man would be of any effects on others in the execution of his own will.

And therefore, because the king's commandment was urgent,.... Or was ordered to be obeyed in haste, and with expedition and dispatch, hence the men were cast into the furnace with clothes on; or those that cast them were not so careful of themselves:
and the furnace exceeding hot; being heated seven times more than usual:
the flame of the fire slew those men that took up Shadrach, Meshach, and Abednego; which came out of the furnace, being so excessive hot, and the smoke along with it; so that when those men took up the three children, and brought them so near to it as was necessary to cast them in, the flame and smoke catched their breath, and suffocated them; who might be men that advised the king to such cruel measures, or however were very ready, out of ill will to these good men, to execute them, and therefore righteously perished in their sins: in the Apocrypha it is said, that the flame issued out forty nine cubits above the furnace.
"So that the flame streamed forth above the furnace forty and nine cubits.'' Song of the Three Holy Children 1:24

flame . . . slew those men-- (Daniel 6:24; Psalm 7:16).

דּי מן (because that), a further explanatory expression added to דּנה כּל־קבל (wholly for this cause): because the word of the king was sharp, and in consequence of it (ו), the furnace was heated beyond measure for that reason. The words אלּך גּבריּא (these mighty men) stand here in the status absol., and are again taken up in the pronoun המּון after the verb קטּל. If the three were brought up to the furnace, it must have had a mouth above, through which the victims could be cast into it. When heated to an ordinary degree, this could be done without danger to the men who performed this service; but in the present case the heat of the fire was so great, that the servants themselves perished by it. This circumstance also is mentioned to show the greatness of the miracle by which the three were preserved unhurt in the midst of the furnace. The same thing is intended by the repetition of the word מכפּתין, bound, Daniel 3:23, which, moreover, is purposely placed at the close of the passage to prepare for the contrast שׁרין, at liberty, free from the bonds, Daniel 3:25.
(Note: Between Daniel 3:23 and Daniel 3:24 the lxx have introduced the Prayer of Azariah and the Song of the three men in the fiery furnace; and these two hymns are connected together by a narrative which explains the death of the Chaldeans who threw the three into the furnace, and the miracle of the deliverance of Daniel's friends. Regarding the apocryphal origin of these additions, composed in the Greek language, which Luther in his translation has rightly placed in the Apocrypha, see my Lehr. der Einl. in d. A. Test. 251.)
