Deuteronomy 17:11-13

11According to the sentence of the law which they shall teach thee, and according to the judgment which they shall tell thee, thou shalt do: thou shalt not decline from the sentence which they shall shew thee, to the right hand, nor to the left.

12And the man that will do presumptuously, and will not hearken unto the priest that standeth to minister there before Yhwh thy God, or unto the judge, even that man shall die: and thou shalt put away the evil from Israel.1

13And all the people shall hear, and fear, and do no more presumptuously.
