Two of the Ten Commandments censor sins of the tongue: “You shall not take the name of the Lord your God in vain” and “You shall not bear false witness against your neighbor” (Exo. 20:7, 16).
Of the seven things that are detestable to God, three are sins of speech: a lying tongue, a false witness that lies, and one who sows discord among brethren (Prov. 6:17, 19).
In his tongue talk, James said “a great forest is set on fire by a small spark” (Jas. 3:5). Changing metaphors he said the tongue “is full of deadly poison” (Jas. 3:8).
Watch your mouth.
Silence cannot be repeated.
