18 And it shall be, when he sits 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 And it shall be with him, and he shall read therein all the days of his life: that he may learn to fear the LORD 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: to the end that he may prolong his days in his kingdom, he, and his children, in the midst of Israel.
