'Iniquity' in the Bible

For God's anger is being revealed from Heaven against all impiety and against the iniquity of men who through iniquity suppress the truth. God is angry:

who gave Himself for us to purchase our freedom from all iniquity, and purify for Himself a people who should be specially His own, zealous for doing good works.

And the tongue is a fire. That world of iniquity, the tongue, is placed within us spotting and soiling our whole nature, and setting the whole round of our lives on fire, being itself set on fire by Gehenna.
