Deuteronomy 19:16-19 NLT

“If a malicious witness comes forward and accuses someone of a crime, then both the accuser and accused must appear before the LORD by coming to the priests and judges in office at that time. The judges must investigate the case thoroughly. If the accuser has brought false charges against his fellow Israelite, you must impose on the accuser the sentence he intended for the other person. In this way, you will purge such evil from among you.
