Zechariah 13:4-5

The prophets shall be ashamed every one of his vision That is, of the extraordinary communication which he pretended to have received, when he uttered a prophecy which he knew to be false. Neither shall they wear a rough garment to deceive The true prophets were wont to wear rough or hairy garments, and therefore the false ones did the same, in order to pass off their impostures; but the words here imply that they should do this no longer. But he shall say, I am no prophet The name they so much affected before, they shall quite disown. I am a husbandman; man taught me to keep cattle from my youth Disclaiming all pretensions to the character of a prophet, he shall profess himself to be no other than a plain, ordinary labouring man, employed in husbandry from his youth. Mr. Harmer's observations on this passage, which he justly parallels with the declaration of Amos 1:14, go to show the incompatibility of such active and laborious employments with the retired and sedentary life of those who were trained up in the schools of the prophets, in order to qualify themselves for that profession.
