2 Chronicles 29:10

Now it is in mine heart to make a covenant with the LORD God of Israel, that his fierce wrath may turn away from us.

Now it is in mine heart to make a covenant with ... God. Convinced of the sin and bitter fruits of idolatry, Hezekiah intended to reverse the policy of his father, and to restore, in all its ancient purity and glory, the worship of the true God. His announcement of this resolution at the beginning of his reign attests his sincere piety, and it also proves the strength of his conviction that righteousness exalteth a nation; because, instead of waiting until his throne was consolidated, he devised measures of national reformation at the beginning of his reign, and vigorously faced all the difficulties which, in such a course, he had to encounter, after the people's habits had so long been moulded to idolatry. His intentions were first disclosed to this meeting of the priests and Levites-for the agency of these officials was to be employed in carrying them into effect.
