Deuteronomy 17:19
And it shall be with him, and he shall read therein 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:
And it shall be with him,.... Always, when at home or abroad, sitting on his throne or lying down, or wherever he went, unless in such places where it was not proper to read it, as the Jews observe {o}: and he shall read therein all the days of his life; every day of his life; meditate on it night and day, as a good man does, that he might be well versed in it, and know how to govern his people according to it:
that he may learn to, fear the Lord his God; to serve and worship him both internally and externally, he having the fear of God always before his eyes, and on his heart, which the holy law of God directs to and instructs in:
to keep all the words of this law, and these statutes, to do them; not only such as concerned him as a king, but all others that concerned him as a man, a creature subject to the Lord, and as an Israelite belonging to the church and commonwealth of Israel, and so includes all laws, moral, ceremonial, and judicial.
