Deuteronomy 17:17-19

New Revised Standard Version, Anglicised

¹⁷ And he must not acquire many wives for himself, or else his heart will turn away; also silver and gold he must not acquire in great quantity for himself. ¹⁸ When he has taken the throne of his kingdom, he shall have a copy of this law written for him in the presence of the levitical priests. ¹⁹ It shall remain with him and he shall read in it all the days of his life, so that he may learn to fear the Lord his God, diligently observing all the words of this law and these statutes,
