Deuteronomy 17:14

11 Acting in agreement with their teaching and the decision they give: not turning to one side or the other from the word they have given you.

12 And any man who, in his pride, will not give ear to the priest whose place is there before the Lord your God, or to the judge, is to be put to death: you are to put away the evil from Israel.

13 And all the people, hearing of it, will be full of fear and put away their pride.

14 When you have come into the land which the Lord your God is giving you, and have taken it for a heritage and are living in it, if it is your desire to have a king over you, like the other nations round about you;

15 Then see that you take as your king the man named by the Lord your God: let your king be one of your countrymen, not a man of another nation who is not one of yourselves.

16 And he is not to get together a great army of horses for himself, or make the people go back to Egypt to get horses for him: because the Lord has said, You will never again go back that way.

17 And he is not to have a great number of wives, for fear that his heart may be turned away; or great wealth of silver and gold.
