Deuteronomy 17:8-10

King James Version

⁸ If there arise a matter too hard for thee in judgment, between blood and blood, between plea and plea, and between stroke and stroke, being matters of controversy within thy gates: then shalt thou arise, and get thee up into the place which the Lord thy God shall choose;

⁹ And thou shalt come unto the priests the Levites, and unto the judge that shall be in those days, and enquire; and they shall shew thee the sentence of judgment:

¹⁰ And thou shalt do according to the sentence, which they of that place which the Lord shall choose shall shew thee; and thou shalt observe to do according to all that they inform thee:
