O king, live for ever - A customary form of address to a monarch, implying that long life was regarded as an eminent blessing. See the notes at Daniel 2:4.

They spake and said to Nebuchadnezzar,.... Having got access unto him, and within his hearing, they expressed themselves in the following manner:

O king, live for ever; this they said to show their fidelity and hearty attachment to him, and their regard to his welfare, and the continuance of his life; and the rather to ingratiate themselves into his affections, and gain audience of him; See Gill on Daniel 2:4.

They spake and said to the king Nebuchadnezzar, O king, live for ever.

9. live for ever-A preface of flattery is closely akin to the cruelty that follows. So Ac 24:2, 3, &c., Tertullus in accusing Paul before Felix.

3:8-18 True devotion calms the spirit, quiets and softens it, but superstition and devotion to false gods inflame men's passions. The matter is put into a little compass, Turn, or burn. Proud men are still ready to say, as Nebuchadnezzar, Who is the Lord, that I should fear his power? Shadrach, Meshach, and Abednego did not hesitate whether they should comply or not. Life or death were not to be considered. Those that would avoid sin, must not parley with temptation when that to which we are allured or affrighted is manifestly evil. Stand not to pause about it, but say, as Christ did, Get thee behind me, Satan. They did not contrive an evasive answer, when a direct answer was expected. Those who make their duty their main care, need not be anxious or fearful concerning the event. The faithful servants of God find him able to control and overrule all the powers armed against them. Lord, if thou wilt, thou canst. If He be for us, we need not fear what man can do unto us. God will deliver us, either from death or in death. They must obey God rather than man; they must rather suffer than sin; and must not do evil that good may come. Therefore none of these things moved them. The saving them from sinful compliance, was as great a miracle in the kingdom of grace, as the saving them out of the fiery furnace was in the kingdom of nature. Fear of man and love of the world, especially want of faith, make men yield to temptation, while a firm persuasion of the truth will deliver them from denying Christ, or being ashamed of him. We are to be meek in our replies, but we must be decided that we will obey God rather than man.
