'Wickedness' in the Bible

So get rid of all uncleanness and all that remains of wickedness, and with a humble spirit receive the word [of God] which is implanted [actually rooted in your heart], which is able to save your souls.

And the tongue is [in a sense] a fire, the very world of injustice and unrighteousness; the tongue is set among our members as that which contaminates the entire body, and sets on fire the course of our life [the cycle of man’s existence], and is itself set on fire by hell (Gehenna).
