John Gill Commentary 2 Chronicles 31:20

"And thus did Hezekiah throughout all Judah; and he wrought that which was good and right and faithful before Jehovah his God." — 2 Chronicles 31:20 (ASV)

And thus did Hezekiah throughout all Judah
Settled the courses of the priests and Levites, and made a provision for them and their families:

and wrought that which was good and right and truth before the Lord his
God :
or did that which was truly right and good, according to the law and will of God, in the sincerity and uprightness of his soul, and as in the presence of the omniscient God, he approving and accepting it for Christ's sake.
