To "give false witness" would include lying in court which is called perjury. Telling false gossip which harms someone is similar. Some think this commandment includes all lying. It is to knowingly give any false statement. Others allow a white lie. Some Jewish teachers said that not all lying is false witness (perjury). They say that lying is sometimes "permissible or even commendable". This would include changing the truth to be modest or to avoid harm to someone. Saint Augustine believed that some lies could be pardoned, and that there were in fact occasions when lying would be the right thing to do. He says that lies which hurt nobody and benefit someone may be forgiven. These need to used with great caution, however.
