Deuteronomy 17:13

10 You 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.

11 According 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.

12 The 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.

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

14 When 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,”

15 you 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.

16 Only 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.”
