But if not, be it known to you, O king, that we will not serve your gods, nor worship the image which you have set up.

Cyprian of Carthage
AD 258
They believed that they might escape according to their faith, but they added, “and if not,” that the king might know that they could also die for the God they worshipped. For this is the strength of courage and of faith, to believe and to know that God can deliver from present death, and yet not to fear death nor to give way, that faith may be the more mightily proved. The uncorrupted and unconquered might of the Holy Spirit broke forth by their mouth, so that the words which the Lord in His Gospel spoke are seen to be true: “But when they shall seize you, take no thought what ye shall speak; for it shall be given you in that hour what ye shall speak. For it is not ye that speak, but the Spirit of your Father which speaketh in you.”
He. Chaldean, "not "(Calmet)
By this modest yet resolute answer, they testified their faith in God's power, and their determination rather to suffer death (Worthington) than to go against their conscience. (Haydock)
They were ignorant whether God would preserve them from the flames or not, (Worthington) as he is said to have rescued Abraham from a similar danger, 2 Esdras ix. 7.
Whether we wish to read "statue" as Symmachus does, or "golden image" as the other authorities have rendered it, those who reverence God are not to worship it. Therefore let judges and princes who worship the statues of emperors or idols realize that they are doing precisely the thing which the three youths refused to do and thereby pleased God. And we should observe the proper significance of the issue involved: they assert that worshipping the mere image is equivalent to serving the false gods themselves, neither of which things is befitting to the servants of God.
a phrasing which admirably avoids the idea, "If He is not able," which would be inconsistent with what they had just asserted, "He is able to deliver us" ---- but rather they say, "If He does not will to do so." Thereby they indicate that it will not be a matter of God's inability but rather of His sovereign will if they do perish.
