Deuteronomy 17:4-6

21st Century King James Version

⁴ and it be told thee, and thou hast heard of it and inquired diligently, and behold, it be true and the thing certain that such abomination is wrought in Israel,

⁵ then shalt thou bring forth that man or that woman who has committed that wicked thing unto thy gates, even that man or that woman, and shalt stone them with stones till they die.

⁶ At the mouth of two witnesses or three witnesses shall he that is worthy of death be put to death, but at the mouth of one witness he shall not be put to death.
