As if we needed anymore proof…
From John Calvin’s Commentary On Nahum 3:5-6
And this passage ought to be especially noticed; for, as I have said, true dignity is not to be found in the highest princes. Princes ought, indeed, to seek respect for themselves by justice, integrity, mercy, and a magnanimous spirit: but they only excel in mean artifices; then they shamelessly deceive, lie, and swear falsely; they also flatter, even meanly, when circumstances require; they insinuate themselves by various crafty means, and by large promises decoy the simple. Since then their true dignity is not commonly regarded by princes, this passage ought to be observed, so that we may know that their elevation, which captivates the minds of men, is an abomination before God; for they do not discern things, but are blind, being dazzled by empty splendor.
And the nakedness of great kings is shown to the nations when the Lord executes his vengeance: for then even the lowest of the low will dare to pass judgment, — “He deserved to perish with shame, for he exercised tyranny on his own subjects, and spared not his own neighbors; he never was a good prince; nay, he only employed deceits and perjuries.” When, therefore princes are cast down, every one, however low, becomes a judge, and ascends as it were, the tribunal to burden and load them with reproaches. And hence the Prophet says, in the person of God, Disclose will I thy fringes on thy face, and will show to the nations thy nakedness, and to kingdoms thy filthiness.
He afterwards adds, I will besprinkle thee with filth, or defilements. The Prophet still alludes to the similitude of a harlot, who is well and sumptuously adorned, and by her charms captivates the eyes of all: but when any one takes mire and filth from the middle of the road, and bespatters her with it, there is then no one who will not turn away his eyes from so filthy an object. But we have already explained the import of this. God is indeed said to besprinkle kingdoms with defilements, when he casts them down; for they all begin freely to express their opinion: and those who before pretended great admiration, now rise up and bring forth many reproachful things. Then it is, that the Lord is said to besprinkle great kingdoms with filth and defilements.
