Zechariah 13:1-2

In that day there shall be a fountain opened to the house of David and to the inhabitants of Jerusalem for sin and for uncleanness. {uncleanness: Heb. separation for uncleanness} And it shall come to pass in that day, saith the LORD of hosts, {that} I will cut off the names of the idols out of the land, and they shall no more be remembered: and also I will cause the prophets and the unclean spirit to pass out of the land.
