Deuteronomy 17:15-17

New Century Version

¹⁵ Be sure to appoint over you the king the Lord your God chooses. He must be one of your own people. Do not appoint as your king a foreigner who is not a fellow Israelite. ¹⁶ The king must not have too many horses for himself, and he must not send people to Egypt to get more horses, because the Lord has told you, “Don’t return that way again.” ¹⁷ The king must not have many wives, or his heart will be led away from God. He must not have too much silver and gold.
