Deuteronomy 19:15-17

Amplified Bible

¹⁵ “A single witness shall not appear in a trial against a man for any wrong or any sin which he has committed; [only] ^[a]on the testimony or evidence of two or three witnesses shall a charge be confirmed. ¹⁶ If a malicious witness rises up against a man to [falsely] accuse him of wrongdoing, ¹⁷ then both parties to the controversy shall stand before the Lord, before the priests and the judges who will be in office at that time.
