11 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.
11 Act according to whatever they teach you and the decisions they give you. Do not turn aside from what they tell you, to the right or to the left.
11 According to the instructions that they give you, and according to the decision which they pronounce to you, you shall do. You shall not turn aside from the verdict that they declare to you, either to the right hand or to the left.
11 Follow their instructions precisely: Don't leave out anything; don't add anything.
11 According to the sentence of the law in which they instruct you, according to the judgment which they tell you, you shall do; you shall not turn aside to the right hand or to the left from the sentence which they pronounce upon you.
11 After they have interpreted the law and declared their verdict, the sentence they impose must be fully executed; do not modify it in any way.

Commentary on Deuteronomy 17:8-13
(Read Deuteronomy 17:8-13)
Courts of judgment were to be set up in every city. Though their judgment had not the Divine authority of an oracle, it was the judgment of wise, prudent, experienced men, and had the advantage of a Divine promise.
