And you shall do all that they instruct you
You must do everything that your authorities command you to do.
("And you shall do according to the word that they shall tell you from that place which the Lord shall choose, and you shall be careful to do according to all that they shall teach you" - Deuteronomy 17:11, and so: "The interpreter and the teacher of the words of the Torah, said, And you shall be careful to do according to all that they shall teach you according to the Torah which they shall teach you," meaning that he would not think in himself to say, "A Pharisee is a good man." "And whoever sits down receives more than the 'hapi' that the Sanhedrin does" - Abarbanel, Devarim, Chapter 17)
