Chronicles II 17:9 Meaning and Commentary

2 Chronicles 17:9

And they taught in Judah
The people their duty to God and man:

and had the book of the law of the Lord with them;
as the rule of their instruction, and the people's obedience; out of this they taught them, and by it confirmed what they taught, and enforced it with the divine authority:

and went about throughout all the cities of Judah;
not only their own cities, the Levitical ones, but all others:

and taught the people;
the law of the Lord, the fear and worship of God.
