“These six things doth the LORD hate: yea, seven are an abomination unto him: An heart that deviseth wicked imaginations, feet that be swift in running to mischief, A false witness that speaketh lies, and he that soweth discord among brethren.” - Proverb 6:16-19.
Those who spread lies about other people, and those who readily believe them and help spread such tales are committing abominations against God. The way to put gossips and tale bearers out of business is to shun them, and refuse to give ear to their talk. Or one could insist on verifying the information from the person who is spoken about. “The north wind driveth away rain: so doth an angry countenance a backbiting tongue.” (Proverbs 25:23) Those who are given to ungodliness, hate those who are righteously inclined and so go about talking ill of them. In the words of Apostle James, those who condemn those keeping the law, have by so doing, made themselves judges, even of the law. He stated: “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. There is one lawgiver, who is able to save and to destroy: who art thou that judgest another?” - James 4:11-12.
Moreover, St. Peter stated, “For the time past of our life may suffice us to have wrought the will of the Gentiles, when we walked in lasciviousness, lusts, excess of wine, revellings, banquetings, and abominable idolatries: Wherein they think it strange that ye run not with them to the same excess of riot, speaking evil of you: Who shall give account to him that is ready to judge the quick and the dead.” - 1 Peter 4:3-5.
