Deuteronomy 17:5

³and they should go and serve other gods, and worship them, the sun, or the moon, or any of the host of heaven, which he commanded thee not to do,

⁴and it be told thee, and thou shalt have inquired diligently, and, behold, the thing really took place, this abomination has been done in Israel;

— Deuteronomy 17:5 —

⁶He shall die on the testimony of two or three witnesses; a man who is put to death shall not be put to death for one witness.

⁷And the hand of the witnesses shall be upon him among the first to put him to death, and the hand of the people at the last; so shalt thou remove the evil one from among yourselves.
