One witness is not enough to convict a man accused of any crime or offense he may have committed. A matter must be established by the testimony of two or three witnesses.116
If a malicious witness2 takes the stand to accuse a man of a crime,
the two men involved in the dispute must stand in the presence of the LORD before the priests and the judges3 who are in office at the time.
The judges must make a thorough investigation,4 and if the witness proves to be a liar, giving false testimony against his brother,
then do to him as he intended to do to his brother.5 You must purge the evil from among you.
