Zechariah 13:4

How then is it, that many are still immersed in their own errors? Because they wish to be so; they close their own eyes against clear light. The kings themselves, and such as exercise authority in the world, desire to be in their filth, and are indifferent as to any kind of abomination; for they fear lest in case of any innovation the common people should take occasion to raise tumults. As they themselves wish to remain quiet, hence it is that they defend with a diabolical pertinacity those superstitions which are abundantly proved to be so. And the people themselves neither care for God nor for their own salvation. Hence then it is, that almost all, from the least to the greatest, regard these asses, who are called prelates, as the most ignorant, and yet they submit to their tyranny. However this may be, the Lord has yet discovered the shame of those who had been a little while ago almost adored.

This is what Zechariah now declares, Ashamed, he says, shall all the Prophets be in that day, every one for his own vision, when they shall have prophesied. And the concession, of which we have spoken, is not without reason; for when the brawling monks about thirty years ago ascended their pulpits, or the prelates, who theatrically acted their holy rites, there was nothing, but what was divine and from heaven. Hence with great impudence they boasted themselves to be God’s messengers, his ministers, vicars, and pastors; though the name of pastors was almost mean in their esteem; but they were Christ’s vicars, they were his messengers, in short, there was nothing which they dared not to claim for themselves. The Prophet ridicules this sort of pride, and seems to say, “Well, let all their trumperies be prophecies; and all their babblings, let these be for a time counted oracles: but when they shall thus prophesy, the Lord will at length make them ashamed, every one for his vision.”

It follows, And they shall not wear a hairy garment that they may lie; that is, they shall not be solicitous of retaining their honor and fame, but will readily withdraw from courting that renown which they had falsely attained. It appears from this place that Prophets wore sordid and hairy garments. Yet interpreters do not appropriately quote those passages from the Prophets where they are bidden to put on sackcloth and ashes; for Isaiah, while announcing many of his prophecies, did not put on sackcloth and ashes, except when he brought some sad message. The same also may be said of Jeremiah, when he was bidden to go naked. But it was a common thing with the Prophets to be content with a hairy, that is, with a sordid and mean garment. For though there is liberty allowed in external things, yet some moderation ought to be observed; for were I to teach in a military dress, it would be deemed inconsistent with common sense. There is no need of being taught as to what common decency may requite. The true Prophets accustomed themselves to hairy garments in order to show that they were sparing and frugal in their clothing as well as in their diet: but they attached no sanctity to this practice, as though they acquired some eminence by their dress, like the monks at this day, who deem themselves holy on account of their hoods and other trumperies. This was not then the object of the Prophets; but only that by their dress they might show that they had nothing else in view but to serve God, and so to separate themselves from the world, that they might wholly devote themselves to their ministry. Now the false Prophets imitated them; hence Zechariah says, they shall no more wear a hairy garment, that is, they shall no more assume a prophetic habit.

His purpose was, not to condemn the false Prophets for wearing that sort of garment, as some have supposed, who have laid hold of this passage for the purpose of condemning long garments and whatever displeased their morose temper; but the Prophet simply means, that when purity of doctrine shall shine forth, and true religion shall attain its own honor, there will be then no place given to false teachers; for they will of themselves surrender their office, and no longer try to deceive the unwary. This is the real meaning of the Prophet: hence he says, that they may lie. We then see that hairy garments are condemned on account of a certain end — even that rapacious wolves might be concealed under the skin of sheep, that foxes might introduce themselves under an appearance not their own. This design, and not the clothing itself, is what is condemned by Zechariah. He afterwards adds —
