Musar zu Dewarim 17:9

Therefore, a man should direct his mind to the will of the Creator, may He be Blessed. And he ought not to rebel against his teachers and against his superiors in Wisdom. And so it is said in the Torah "And thou shalt come unto the priests the Levities, and unto the judge that shall be in those days; and thou shalt inquire; and they shall declare unto thee the sentence of judgment. And thou shalt do according to the tenor of the sentence, which they shall declare unto thee… thou shalt not turn aside from the sentence which they shall declare unto thee, to the right and, nor to the left. And the man that doeth presumptuously, in not hearkening unto the priest that standeth to minister there before the Lord thy God, or unto the judge, even that man shall die; and thou shalt exterminate the evil from Israel" (Deut. 17:9-12).
