Deuteronomy 17:2-5

If there be found in the midst of thee, within any of thy gates which Jehovah thy God giveth thee, man or woman, that doeth that which is evil in the sight of Jehovah thy God, in transgressing his covenant, and hath gone and served other gods, and worshipped them, or the sun, or the moon, or any of the host of heaven, which I have not commanded, and it be told thee, and thou hast heard of it; then shalt thou inquire diligently; and, behold, if it be true, and the thing certain, that such abomination is wrought in Israel, then shalt thou bring forth that man or that woman, who hath done this evil thing, unto thy gates, even the man or the woman; and thou shalt stone them to death with stones.
