Zechariah 13:4

And it shall come to pass in that day, that the prophets shall be ashamed every one of his vision, when he hath prophesied; neither shall they wear a rough garment to deceive:

The prophets shall be ashamed - of the false prophecies which they have uttered in times past, and which the event has confuted.

Neither shall they wear a rough garment - sackcloth. The badge of a prophet (; ), to mark their frugality alike in food and attire. Such as Elijah and his antitype, John the Baptist, wore (); also, to be consonant to the mournful warnings which they delivered.

To deceive. It is not the dress that is here condemned, but the purpose of deception for which it was worn-namely, to conceal wolves under sheep's clothing (Calvin). The monkish hair-shirt of Popery, worn to inspire the multitude with the impression of superior sanctity, shall be then cast aside.
