And like unto him was there no king before him,.... The same is said of Hezekiah, 2 Kings 18:5, Hezekiah might excel him in some things, as Josiah might excel Hezekiah in others:
that turned to the Lord with all his heart, and with all his soul, and with all his might; with such sincerity, heartiness, zeal, and constancy:
according to all the law of Moses; having respect to every commandment, especially relative to worship, with the greatest precision and exactness:
neither after him arose there any like him; for all to the captivity were wicked princes.
