Then said Daniel unto the king, O king, live forever - The common form of salutation in addressing the king. See the note at Daniel 2:4. There might be more than mere form in this, for Daniel may have been aware of the true source of the calamities that had come upon him, and of the innocence of the king in the matter; and he doubtless recalled the interest which the king had shown in him when about to be cast into the den of lions, and his expression of confidence that his God would be able to deliver him Daniel 6:16, and he could not but have been favorably impressed by the solicitude which the monarch now showed for his welfare in thus early visiting him, and by his anxiety to know whether he were still alive.

Then said Daniel unto the king,.... Whose voice he knew, though the tone of it was so much altered:

O king, live for ever; he does not reproach him for delivering him into the hands of his enemies, and suffering him to be cast into that place, which he might have prevented, had he had more resolution; he knew it was done with reluctance, though with weakness; which he does not upbraid him with, but freely forgives him, and wishes him health, long life, and prosperity.

Then said Daniel unto the king, O king, live for ever.

21. Daniel might have indulged in anger at the king, but does not; his sole thought is, God's glory has been set forth in his deliverance.

6:18-24 The best way to have a good night, is to keep a good conscience. We are sure of what the king doubted, that the servants of the living God have a Master well able to protect them. See the power of God over the fiercest creatures, and believe his power to restrain the roaring lion that goeth about continually seeking to devour. Daniel was kept perfectly safe, because he believed in his God. Those who boldly and cheerfully trust in God to protect them in the way of duty, shall always find him a present help. Thus the righteous is delivered out of trouble, and the wicked cometh in his stead. The short triumph of the wicked will end in their ruin.
