Deuteronomy 17:15–19

15When that happens, make sure you appoint over you the king the Lord your God chooses. He must be from among your own people. Don’t appoint over you someone from another country. Don’t choose anyone who isn’t from one of the tribes of Israel.

16The king must not get large numbers of horses for himself. He must not make the people return to Egypt to get more horses. The Lord has told you, “You must not go back there again.”

17The king must not have a lot of wives. If he does, he will be led down the wrong path. He must not store up large amounts of silver and gold.

18When he sits on the throne of his kingdom, he must make himself a copy of the law I’m teaching you. He must write it on a scroll. He must copy it from the scroll of a priest, who is a Levite.

19The king must keep the scroll close to him at all times. He must read it all the days of his life. Then he can learn to have respect for the Lord his God. He can carefully follow all of the words of that law and those rules.
