Deuteronomy 17:10

and thou shalt act according to what they declare to thee from the place which the Lord thy God hath chosen, and thou shalt be careful to do according to what is expounded to thee for law.

And thou shalt act according to the thing which they shall report to thee out of the place which the Lord thy God shall choose, and thou shalt observe to do all whatsoever shall have been by law appointed to thee.
