Deuteronomy 17:4

You shall not sacrifice to the LORD your God an ox or a sheep in which is a defect or anything evil; for that is an abomination to the LORD your God.

If there is found among you, within any of your gates which the LORD your God gives you, a man or woman who does that which is evil in the LORD your God’s sight in transgressing his covenant,

and has gone and served other gods and worshiped them, or the sun, or the moon, or any of the stars of the sky, which I have not commanded,

then you shall bring out that man or that woman who has done this evil thing to your gates, even that same man or woman; and you shall stone them to death with stones.

At the mouth of two witnesses, or three witnesses, he who is to die shall be put to death. At the mouth of one witness he shall not be put to death.

The hands of the witnesses shall be first on him to put him to death, and afterward the hands of all the people. So you shall remove the evil from among you.
