Zechariah 13:5 - Albert Barnes' Notes on the Bible

And he shall say - Repudiating his former claims, “I am a husbandman:” for a man hath taught me from my youth.” There was no room then for his having been a false prophet, since he had had from his youth one simple unlettered occupation, as Amos said truly of himself; “I was no prophet, neither was I a prophet’s son: but I was an herdsman and a gatherer of sycamore fruit” Amos 7:14. The prophet does not approve the lie, any more than our Lord did the injustice of the “unjust steward.” Our Lord contrasted the wisdom “in their generation” of a bad man for his ends, with the unwisdom of “the children of light,” who took no pains to secure their God. Zechariah pictures vividly, how people would anyhow rid themselves of all suspicion of false prophesying.
