'Unclean' in the Bible

Who having no more power of feeling, have given themselves up to evil passions, to do all unclean things with overmuch desire.

But evil acts of the flesh and all unclean things, or desire for others' property, let it not even be named among you, as is right for saints;

For this ye know, that no whoremonger, nor unclean person, nor covetous man, who is an idolater, hath any inheritance in the kingdom of Christ and of God.
