Bible Verses About Kings: Required to write and keep by them, a copy of the divine law

"When he has come to occupy the throne of his kingdom, he is to write a copy of this Torah for himself in a scroll, from the one the cohanim and L'vi'im use.

It is to remain with him, and he is to read in it every day, as long as he lives; so that he will learn to fear ADONAI his God and keep all the words of this Torah and these laws and obey them;

so that he will not think he is better than his kinsmen; and so that he will not turn aside either to the right or to the left from the mitzvah. In this way he will prolong his own reign and that of his children in Isra'el.
