Deuteronomy 17:18-20 Webster Bible Translation (WBT)

18. And it shall be when he sitteth upon the throne of his kingdom, that he shall write him a copy of this law in a book out of that which is before the priests the Levites.

19. And it shall be with him, and he shall read in 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:

20. That his heart may not be lifted above his brethren, and that he may 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.
