23:2 Prophets - Either Jeremiah, Zephaniah, Urijah: or, the sons of the prophets. It seems he read it himself. Josiah did not think it beneath him, to be a reader, any more than Solomon did to be a preacher, and David to be even a door keeper in the house of God. All people are concerned to know the scripture, and all in authority, to spread the knowledge of it.
23:1-3 Josiah had received a message from God, that there was no preventing the ruin of Jerusalem, but that he should only deliver his own soul; yet he does his duty, and leaves the event to God. He engaged the people in the most solemn manner to abolish idolatry, and to serve God in righteousness and true holiness. Though most were formal or hypocritical herein, yet much outward wickedness would be prevented, and they were accountable to God for their own conduct.
