Deuteronomy 17
18 Ref And it shall be, when he sitteth upon the throne of his kingdom, that he shall write him a copy of this law in a book, out of `that which is' before the priests the Levites:
19 Ref 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 Ref 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: to the end that he may prolong his days in his kingdom, he and his children, in the midst of Israel.
