2 And the king went up into the house of Jehovah, and all the men of Judah and all the inhabitants of Jerusalem with him, and the priests and the prophets, and all the people, both small and great; and he read in their ears all the words of the book of the covenant which had been found in the house of Jehovah.
Matthew Henry's Commentary on 2 Kings 23:2
Commentary on 2 Kings 23:1-3
(Read 2 Kings 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.
