Deuteronomy 17:13

9 You are to go to the Levitical priests and to the judge who presides at that time. Inquire of them, and they will give you a verdict in the case.

10 You must abide by the verdict they give you at the place the LORD will choose. Be careful to do everything they instruct you,

11 according to the terms of law they give and the verdict they proclaim. Do not turn aside to the right or to the left from the decision they declare to you.

12 But the man who acts presumptuously, refusing to listen either to the priest who stands there to serve the LORD your God, or to the judge, must be put to death. You must purge the evil from Israel.

13 Then all the people will hear and be afraid, and will no longer behave arrogantly.

14 When you enter the land that the LORD your God is giving you and have taken possession of it and settled in it, and you say, “Let us set a king over us like all the nations around us,”

15 you are to appoint over yourselves the king whom the LORD your God shall choose. Appoint a king from among your brothers; you are not to set over yourselves a foreigner who is not one of your brothers.

16 But the king must not acquire many horses for himself or send the people back to Egypt to acquire more horses, for the LORD has said, ‘You are never to go back that way again.’

17 He must not take many wives for himself, lest his heart go astray. He must not accumulate for himself large amounts of silver and gold.
