Deuteronomy 17:18-20

“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. 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, 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.
