Matthew Henry on 2 Chronicles 35

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 Jewish 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 belonging to us, in doing which we obtain this blessing from the Lord.

The Scripture does not condemn Josiah's conduct in opposing Pharaoh. Yet Josiah seems to deserve blame for not inquiring of the Lord after he was warned; his death might be a rebuke for his rashness, but it was a judgment on a hypocritical and wicked people. He that lives a life of repentance, faith, and obedience, cannot be affected by the sudden manner in which he is removed. The people lamented him. Many mourn over sufferings, who will not forsake the sins that caused God to send them. Yet this alone can turn away judgments. If we blame Josiah's conduct, we should be watchful, lest we be cut down in a way dishonourable to our profession.
