Deuteronomy 19:16

If a false witness rise up against any man to testify against him that which is wrong;

Deuteronomy 19:16 stands in Deuteronomy 5 to 26, which is Moses's review of the law for the new generation given just before his death, from which the book takes its name meaning second law or duplicate of the law, and it belongs to the Deuteronomy 18 to 21 portion set for March 4. A false witness is someone who rises up to testify against another person what is false and wrong. A matter must be proved by two or three agreeing witnesses, not by one witness alone.

A charge of false testimony must be examined through a regular trial, with witnesses summoned and the accusers given time to appear. If the testimony is proved false, the false witness must receive the punishment he intended to bring upon the accused, the penalty the accused would have received if convicted. This equal penalty guards people's lives, property, and reputations against false testimony and protects them from false charges. The requirement makes witnesses answerable for their testimony and calls them to be willing to bear the penalty for false testimony.
