"A single witness can never be enough to convict someone of any crime, any offense, any wrongdoing. A charge can only be established on the testimony of two or three witnesses.
If a malicious witness comes forward to accuse someone falsely, both parties must stand before the Lord — before the priests and judges serving at that time. The judges must investigate thoroughly.
And if the witness is lying — if they've falsely accused their brother — then do to them exactly what they intended to do to the accused. Purge the evil from among you.
Everyone else will hear about it and be afraid. No one will dare do something like that again.
Show no pity. Life for life, eye for eye, tooth for tooth, hand for hand, foot for foot."
