Daniel 3:25

“He answered and said, lo, I see four men loose, etc.] Not bound as the three were, when cast in; but quite at liberty in their hands and feet, and separate from one another. As this fiery furnace may be an emblem of the fiery trials and afflictive dispensations the children of God pass through in this world, being not joyous, but grievous to the flesh, though useful to purge and purify; so this and some other circumstances attending these good men in the furnace are applicable to the saints in such cases; for though afflictions are sometimes themselves called cords, with which men are said to be bound, yet by means of them they are loosed from other things from the power and prevalence of…”

“four--whereas but three had been cast in. loose--whereas they had been cast in "bound." Nebuchadnezzar's question, in Dan 3:24, is as if he can scarcely trust his own memory as to a fact so recent, now that he sees through an aperture in the furnace what seems to contradict it. walking in . . . midst of . . . fire--image of the godly unhurt, and at large (Joh 8:36), "in the midst of trouble" (Psa 138:7; compare Psa 23:3-4). They walked up and down in the fire, not leaving it, but waiting for God's time to bring them out, just as Jesus waited in the tomb as God's prisoner, till God should let Him out (Act 2:26-27). So Paul (Co2 12:8-9). So Noah waited in the ark, after the flood, till God…”

“He answered and said, Lo, I see four men loose - From the fact that he saw these men now loose, and that this filled him with so much surprise, it may be presumed that they had been bound with something that was not combustible - with some sort of fetters or chains. In that case it would be a matter of surprise that they should be “loose,” even though they could survive the action of the fire. The “fourth” personage now so mysteriously added to their number, it is evident, assumed the appearance of a “man,” and not the appearance of a celestial being, though it was the aspect of a man so noble and majestic that he deserved to be called a son of God. Walking in the midst of the fire - The…”

“No hurt - See how the God of nature can when he pleases control the powers of nature! The Son of God - Probably he had heard David speak of him. Jesus Christ, the Angel of the covenant, did sometimes appear before his incarnation. Those who suffer for Christ, have his gracious presence with them in their sufferings, even in the fiery furnace, even in the valley of the shadow of death, and therefore need fear no evil. Daniel 3:26”

“3:25 walking around: The same word is used in Gen 3:8-9. • like a god (literally like a son of the gods): The king understood the being as the Lord’s angel (Dan 3:28).”

“walking: Isa 43:2 they have no hurt: Chal, there is no hurt in them, Psa 91:3-9; Mar 16:18; Act 28:5; Pe1 3:13 the Son of God: Or, as bar elahin may be rendered, "a son of the gods," i.e., a divine person or angel. Dan 3:18, Dan 3:28; Job 1:6, Job 38:7; Psa 34:7; Pro 30:4; Luk 1:35; Joh 19:7, Joh 19:8; Rom 1:4 Daniel 3:26”
