Deuteronomy 17:8, 18

“If any case is too difficult for you to decide, between one kind of homicide or another, between one kind of lawsuit or another, and between one kind of assault or another, being cases of dispute in your courts, then you shall arise and go up to the place which the LORD your God chooses.

“Now it shall come about when he sits on the throne of his kingdom, he shall write for himself a copy of this law on a scroll in the presence of the Levitical priests.
