John Gill's Bible Commentary Ver. 2. And he set the priests in their charges , etc.] In their offices, and in their proper places, to execute them: and encouraged them to the service of the house of the Lord ; to attend it with cheerfulness and constancy, and do it according to the will of God, promising his favour and protection.
Matthew Henry Commentary
Verses 1-19 - The destruction Josiah made of idolatry, was more largely related in the book of Kings. His solemnizing the passover is related here. The Lord's supper resembles the passover more than any other of the Jewis festivals; and the due observance of that ordinance, is a proof of growing piety and devotion. God alone can truly make our hearts holy and prepare them for his holy services; but there are duties belongin to us, in doing which we obtain this blessing from the Lord.
