Zechariah 13:2-4

2And on that day, declares the LORD of Hosts, I will erase the names of the idols from the land, and they will no longer be remembered. I will also remove the prophets and the spirit of impurity1 from the land.

3And if anyone still prophesies, his father and mother who bore him will say to him, ‘You shall not remain alive, because you have spoken falsely in the name of the LORD.’ When he prophesies, his father and mother who bore him will pierce him through.

4And on that day every prophet who prophesies will be ashamed of his vision, and he will not put on a hairy cloak in order to deceive.
