Deuteronomy 17:3-5

Amplified Bible

³ and has gone and served other gods and worshiped them, or the sun or the moon or any of the heavenly host, [doing these things] which I have commanded not to do, ⁴ and if it is told to you and you hear about it, then you shall investigate thoroughly [all the charges]. If it is confirmed ^[a]beyond doubt that this detestable thing has been done in Israel, ⁵ then you shall bring that man or that woman who has done this evil thing to the gates [of your city] and you shall stone the man or the woman to death.
