Deuteronomy 17:10-11

And thou shalt do according to the sentence, which they of that place which the LORD shall choose shall shew thee; and thou shalt observe to do according to all that they inform thee:

According 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.
