Zechariah 13:2-3

2“On that day, I will banish the names of the idols from the land, and they will be remembered no more,” declares the Lord Almighty. “I will remove both the prophets and the spirit of impurity from the land. 3And if anyone still prophesies, their father and mother, to whom they were born, will say to them, ‘You must die, because you have told lies in the Lord’s name.’ Then their own parents will stab the one who prophesies.
