Deuteronomy 17:17-19

Darby Translation

¹⁷ Neither shall he multiply wives to himself, that his heart turn not away; neither shall he greatly multiply to himself silver and gold.

¹⁸ And it shall be, when he sitteth upon the throne of his kingdom, that he shall write for himself a copy of this law in a book out of that which is before the priests, the Levites;

¹⁹ and it shall be with him, and he shall read therein all the days of his life; that he may learn to fear Jehovah his God, to keep all the words of this law and these statutes, to do them;
