Deuteronomy 17:19-20

21st Century King James Version

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.
