Zechariah 13
"In that day a fountain shall be opened for the house of David and for the people of Jerusalem for [cleansing from] sin and impurity.
"In that day," declares the LORD of hosts, "I will cut off the names of the idols from the land, and they will no longer be remembered. I will also remove the [false] prophets and the unclean spirit from the land.
And if anyone still [appears as a prophet and falsely] prophesies, then his father and his mother who gave birth to him will say to him, 'You shall not live, for you have spoken lies in the name of the LORD'; and his father and his mother who gave birth to him shall pierce him through when he prophesies.
And 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,
but 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.'
