Deuteronomy 17:18-20 Darby Translation 1890 (DARBY)

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;

20. that his heart be not lifted up above his brethren, and that he turn not aside from the commandment, to the right hand, or to the left; that he may prolong his days in his kingdom, he, and his sons, in the midst of Israel.
