James 3:2-8

Amplified Bible

² For we all stumble and sin in many ways. If anyone does not stumble in what he says [never saying the wrong thing], he is a perfect man [fully developed in character, without serious flaws], able to bridle his whole body and rein in his entire nature [taming his human faults and weaknesses]. ³ Now if we put bits into the horses’ mouths to make them obey us, we guide their whole body as well. ⁴ And look at the ships. Even though they are so large and are driven by strong winds, they are still directed by a very small rudder wherever the impulse of the helmsman determines. 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). ⁷ For every species of beasts and birds, of reptiles and sea creatures, is tamed and has been tamed by the human race. ⁸ But no one can tame the human tongue; it is a restless evil [undisciplined, unstable], full of deadly poison.
