Jerome
Patristic
c. A.D. 347–420
“Verse 17. "For behold, our God whom we serve is able to rescue us from the furnace of burning fire and to free us from thy hands, O king!" Where he had imagined he was frightening mere youths, he perceives in them a nature of manly courage. Nor do they speak of deliverance as delayed to the distant future, but rather they promise themselves immediate succor, asserting, "For behold, our God whom we serve is the One who is able to free us both from the fearsome flames thou threatenest and from thy hands."”
