Deuteronomy 17:13

9You shall come to the priests who are Levites and to the judge who shall be in those days. You shall inquire, and they shall give you the verdict.

10You shall do according to the decisions of the verdict which they shall give you from that place which the LORD chooses. You shall observe to do according to all that they shall teach you.

11According to the decisions of the law which they shall teach you, and according to the judgment which they shall tell you, you shall do. You shall not turn away from the sentence which they announce to you, to the right hand, nor to the left.

12The man who does presumptuously in not listening to the priest who stands to minister there before the LORD your God, or to the judge, even that man shall die. You shall put away the evil from Israel.

13All the people shall hear and fear, and do no more presumptuously.

14When you have come to the land which the LORD your God gives you, and possess it and dwell in it, and say, “I will set a king over me, like all the nations that are around me,”

15you shall surely set him whom the LORD your God chooses as king over yourselves. You shall set as king over you one from among your brothers. You may not put a foreigner over you, who is not your brother.

16Only he shall not multiply horses to himself, nor cause the people to return to Egypt, to the end that he may multiply horses; because the LORD has said to you, “You shall not go back that way again.”

17He shall not multiply wives to himself, that his heart not turn away. He shall not greatly multiply to himself silver and gold.
