James 3:5-6Amplified Bible (AMP)

⁵ In the same sense, the tongue is a small part of the body, and yet it boasts of great things.
See [by comparison] how great a forest is set on fire by a small spark! ⁶ 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 ^[a]hell (Gehenna).
