Deuteronomy 17:18-20

Amplified Bible

¹⁸ “Now it shall come about when he sits on the throne of his kingdom, he shall write for himself a copy of this law on a scroll in the presence of the Levitical priests. ¹⁹ And it shall be with him and he shall read it all the days of his life, so that he may learn to fear [and worship] the Lord his God [with awe-filled reverence and profound respect], by carefully obeying (keeping foremost in his thoughts and actively doing) all the words of this law and these statutes, ²⁰ so that his heart will not be lifted up above his countrymen [by a false sense of self-importance and self-reliance] and that he will not turn away (deviate) from the commandment, to the right or to the left, so that he and his sons may continue [to reign] for a long time in his kingdom in Israel.
