MSB(i)
18 When he is seated on his royal throne, he must write for himself a copy of this instruction on a scroll in the presence of the Levitical priests.
19 It is to remain with him, and he is to read from it all the days of his life, so that he may learn to fear the LORD his God by carefully observing all the words of this instruction and these statutes.
20 Then his heart will not be exalted above his countrymen, and he will not turn aside from the commandment, to the right or to the left, in order that he and his sons may reign many years over his kingdom in Israel.
