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

It shall be, when he sits on the throne of his kingdom, that he shall write himself a copy of this law in a book, out of that which is before the priests the Levites.

It shall be with him, and he shall read from it 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;

that his heart not be lifted up above his brothers, and that he not turn 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.
