Once seated on his royal throne, and for his own use, he must write a copy of this Law on a scroll, at the dictation of the levitical priests. It must never leave him, and he must read it every day of his life and learn to fear Yahweh his God by keeping all the words of this Law and observing these rules, so that he will not think himself superior to his brothers, and not deviate from these commandments either to right or to left. So doing, long will he occupy his throne, he and his sons, in Israel.
Deut 17: 18 – 20

What is “Fear of the Lord”? It is this: be teachable; observe the laws; worship with the community; because these things enable memory.
