Deuteronomy 17:9-11

New Revised Standard Version, Anglicised Catholic Edition

⁹ where you shall consult with the levitical priests and the judge who is in office in those days; they shall announce to you the decision in the case. ¹⁰ Carry out exactly the decision that they announce to you from the place that the Lord will choose, diligently observing everything they instruct you. ¹¹ You must carry out fully the law that they interpret for you or the ruling that they announce to you; do not turn aside from the decision that they announce to you, either to the right or to the left.
