Deuteronomy 17:11-13 New Revised Standard Version, Anglicised (NRSVA)
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. 12 As for anyone who presumes to disobey the priest appointed to minister there to the Lord your God, or the judge, that person shall die. So you shall purge the evil from Israel. 13 All the people will hear and be afraid, and will not act presumptuously again.
