Reference: Evil Speaking
Hastings
EVIL SPEAKING in the Bible covers sins of untruthfulness as well as of malice. It includes abuse, thoughtless talebearing, imputing of bad motives, slander, and deliberate false witness. Warnings against it are frequent; it is forbidden in the legislation of the OT (Ninth Commandment; De 19:16-19) and of the NT (Mt 5:22; 12:32; 15:19). Christians must expect this form of persecution (Mt 5:11), but must be careful to give no handle to it (Ro 14:16; Tit 2:8; 1Pe 2:12; 3:16).
