The person can only be sentenced to death on the testimony of two or three witnesses, but no one should ever be sentenced to death on the testimony of only one witness.
“Whoever kills another person will be put to death as a murderer only on the testimony of more than one witness. No one can be put to death on the testimony of only one witness.
“Do Moses’ Teachings enable us to judge a person without first hearing that person’s side of the story? We can’t judge a person without finding out what that person has done.”
One witness is never enough to convict someone of a crime, offense, or sin he may have committed. Cases must be settled based on the testimony of two or three witnesses.
