Deuteronomy 17:9-12

9And thou shalt come unto the priests, the Levites, and unto the judge that shall be in those days, and inquire; and they shall declare unto thee the sentence of judgment;

10and thou shalt do according to the tenor of the word, which they of that place which Jehovah will choose shall declare unto thee; and thou shalt take heed to do according to all that they instruct thee:

11according to the sentence of the law which they shall declare unto thee, and according to the judgment which they shall tell thee, thou shalt do: thou shalt not decline from the word which they shall declare unto thee, to the right hand, or the left.

12And the man that shall act presumptuously, and not hearken unto the priest that standeth to serve there before Jehovah thy 1God, or unto the judge, that man shall die; and thou shalt put away evil from Israel.
