Deuteronomy 17:10

New International Version

You must act according to the decisions they give you at the place the Lord will choose. Be careful to do everything they instruct you to do.

See the chapter Copy

and so you can teach the Israelites all the decrees the Lord has given them through Moses.”

Go to the Levitical priests and to the judge who is in office at that time. Inquire of them and they will give you the verdict.

Act according to whatever they teach you and the decisions they give you. Do not turn aside from what they tell you, to the right or to the left.
