Devarim 17:18-20

Orthodox Jewish Bible

¹⁸ And it shall be, when he sitteth upon the kisei mamlakhto (throne of his kingdom), that he shall write him a mishneh hatorah hazot (copy of this torah) in a sefer out of that which is before the kohanim, the Levi’im;

¹⁹ And it shall be with him, and he shall read therein all the days of his life; that he may learn to fear Hashem Elohav, to be shomer over kol divrei hatorah hazot and these chukkim, to do them;

²⁰ That his lev be not lifted up in pride above his brethren, and that he turn not aside from the mitzvah, to the right hand, or to the left; to the end that he may prolong his days in his mamlachah, he, and his banim, in the midst of Yisroel.
