Deuteronomy 17:17-19

New Catholic Bible

¹⁷ He should also not have many wives, lest his heart be turned astray. He must not accumulate large sums of silver or gold. ¹⁸ When he takes the throne of his kingdom, he is to write a copy of the law that is entrusted to the priests, the Levites for himself on a scroll. ¹⁹ He should read it every day of his life so that he can learn to fear the Lord, his God, and to observe all the words of these laws and statutes, fulfilling them.
