Gossip and Talebearing
We think with horror of the cannibal who feasts on the still warm and trembling flesh of his victim; but are the results of even this practice more terrible than are the agony and ruin caused by misrepresenting motive, blackening reputation, dissecting character? Let the children, and the youth as well, learn what God says about these things: “Death and life are in the power of the tongue.” The spirit of gossip and talebearing is one of Satan's special agencies to sow discord and strife, to separate friends, and to undermine the faith of many in the truthfulness of our positions.

James 4:11 KJV
11 Speak not evil one of another, brethren. He that speaketh evil of his brother, and judgeth his brother, speaketh evil of the law, and judgeth the law: but if thou judge the law, thou art not a doer of the law, but a judge.
Ephesians 4:29 KJV
29 Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers.
James 1:26-27 KJV
26 If any man among you seem to be religious, and bridleth not his tongue, but deceiveth his own heart, this man's religion is vain.
27 Pure religion and undefiled before God and the Father is this, To visit the fatherless and widows in their affliction, and to keep himself unspotted from the world.
