Zechariah 13:4-6

4And in that day the [false] prophets will each be ashamed of his vision when he prophesies, and they will not wear a hairy robe [of true prophets] in order to deceive,

5but he will [deny his identity and] say, ‘I am no prophet. I work the ground, because a man sold me as a slave in my youth.’

6And one will say to him, ‘What are these wounds between your arms?’ Then he will answer, ‘Those wounds I received in the house of my friends.’
