2 Chronicles 31:3-4; 2 Chronicles 31:21
The king also made a personal contribution of animals for the daily morning and evening burnt offerings, as well as for the weekly Sabbath festivals and monthly new moon festivals, and for the other annual festivals as required in the law of the LORD.
In addition, he required the people in Jerusalem to bring the prescribed portion of their income to the priests and Levites, so they could devote themselves fully to the law of the LORD.
In all that he did in the service of the Temple of God and in his efforts to follow the law and the commands, Hezekiah sought his God wholeheartedly. As a result, he was very successful.
