Deuteronomy 17:3-5

3and goeth and serveth other 1gods, and boweth down to them, either to the sun or to the moon, or to the whole host of heaven, which I have not commanded;

4and it be told thee, and thou hearest of it; then thou shalt make thorough inquiry, and if it be truth [and] the thing be certain, that this abomination hath been wrought in Israel,

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