'Tongue' in the Bible
If any one think himself to be religious, not bridling his tongue, but deceiving his heart, this man's religion is vain.
Thus also the tongue is a little member, and boasts great things. See how little a fire, how large a wood it kindles!
and the tongue is fire, the world of unrighteousness; the tongue is set in our members, the defiler of the whole body, and which sets fire to the course of nature, and is set on fire of hell.
