False testimony: When a wrong statement is given, then the law foresees punishment, for example if by purpose wrong numbers are shown in the balance sheet in accounting.
As an individual, we may not be punished in that sense for giving a false statement in private life. Yet how many times do we talk bad about others, taking away the honour for example of absent persons? How many times do we hurt others by using bad or aggressive language? Each destructive word, each curse has negative consequences.
