'Uncleanness' in the Bible

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.

And it hath come to pass, in that day, An affirmation of Jehovah of Hosts, I cut off the names of the idols from the land, And they are not remembered any more, And also the prophets and the spirit of uncleanness I cause to pass away from the land.
