Deuteronomy 17:17-19 New Life Version (NLV)
17 He must not take many wives for himself or his heart may turn away. And he must not gather much silver and gold for himself.
18 “When he sits on the throne of his nation, he should write this Law for himself in a book in front of the Levite religious leaders. 19 It should be kept with him and he should read it all the days of his life. Then he will learn to fear the Lord his God, by being careful to obey all the words of these Laws.
