Jonah 3:6

The king preferred to escape in a hair-shirt, rather than to perish in purple garments. We must understand, dearly beloved, that lowliness avails more than power.

A sovereign serves God one way as a man, another way as a king. He serves him as man by living according to faith. He serves him as king by exerting the necessary strength to sanction laws that command goodness and prohibit its opposite. It was thus that Ezekiel served him by destroying the groves and temples of idols and the high places that had been set up contrary to the commandments of God. Thus Josiah served him by performing similar acts. Thus the king of the Ninevites served him by compelling the whole city to appease the Lord.

"For word came unto the king of Nineveh, and he arose from his throne, and he laid his robe from him, and covered him with sackcloth, and sat in ashes. And he caused it to be proclaimed and published through Nineveh by the decree of the king and his nobles, saying, Let neither man nor beast, herd nor flock, taste any thing: let them not feed, nor drink water: But let man and beast be covered with sackcloth, and cry mightily unto God: yea, let them turn every one from his evil way, and from the violence that is in their hands. Who can tell if God will turn and repent, and turn away from his fierce anger, that we perish not?" LXX: 'the message reached the king of Nineveh, and he arose from his throne, took off his robe and covered himself with sackcloth, and he sat down upon the earth. And by the order of the king and his nobles it was announced throughout Nineveh, saying, it is forbidden for any man or beast or oxen or sheep to eat anything, to drink any water. Men and beasts were covered in sackcloth and cried out to the Lord mightily. Let each one turn away from his wicked practises and from the unfairness that was in his hands, saying, who knows if God will turn and repent, if he will not abandon the fierceness of his wrath so that we might not die?'. I know certain men for whom the king of Nineveh, (who is the last to hear the proclamation and who descends from his throne, and forgoes the ornaments of his former vices and dressed in sackcloth sits on the ground, he is not content with his own conversion, preaches penitence to others with his leaders, saying, "let the men and beasts, big and small of size, be tortured by hunger, let them put on sackcloth, condemn their former sins and betake themselves without reservation to penitence!) is the symbol of the devil, who at the end of the world, (because no spiritual creature that is made reasoning by God will perish), will descend from his pride and do penitence and will be restored to his former position. To support this opinion they use this example of Daniel in which Nebuchadnezzar after seven years of penitence is returned to his former reign. [Dan. 4:24, 29, 33] But because this idea is not in the Holy Scripture and since it completely destroys the fear of God, (for men will slide easily into vices if they believe that even the devil, the creator of wickedness and the source of all sins, can be saved…
