When you come to the land the Lord your God is giving you and take it over and live in it and then say, "I will select a king like all the nations surrounding me," you must select without fail a king whom the Lord your God chooses. From among your fellow citizens you must appoint a king -- you may not designate a foreigner who is not one of your fellow Israelites.

Furthermore, he must not marry many wives lest his affections turn aside, and he must not accumulate much silver and gold. When he sits on his royal throne he must make a copy of this law on a scroll given to him by the Levitical priests.

Then he will not exalt himself above his fellow citizens or turn from the commandments to the right or left, and he and his descendants will enjoy many years ruling over his kingdom in Israel.
