False speaking in any matter, every attempt or purpose to deceive our neighbor, is here included. An intention to deceive is what constitutes falsehood. By a glance of the eye, a motion of the hand, an expression of the countenance, a falsehood may be told as effectually as by words. All intentional overstatement, every hint or insinuation calculated to convey an erroneous or exaggerated impression, even the statement of facts in such a manner as to mislead, is falsehood. This precept forbids every effort to injure our neighbor's reputation by misrepresentation or evil surmising, by slander or tale bearing. Even the intentional suppression of truth, by which injury may result to others, is a violation of the ninth commandment.

Dette indbefatter enhver form for løgn, ethvert forsøg på eller plan om at bedrage vor næste. At have til hensigt at bedrage er det samme som falskhed. Ved et øjekast, en håndbevægelse, et ansigtsudtryk kan man give udtryk for falskhed lige så virkeligt som i ord. Enhver tilsigtet overdrivelse, enhver antydning, der har til formål at overdrive eller bibringe et fejlagtigt indtryk, ja, selv fremstilling af kendsgerninger på en vildledende måde er falsk vidnesbyrd. Dette bud forbyder ethvert forsøg på at skade vor næstes rygte ved at stille ham i et dårligt lys eller ved at fremsætte ondsindede formodninger, samt ved at bagtale ham og sladre om ham. Selv en overlagt fortielse af sandheden til skade for andre er overtrædelse af det niende bud.
