3 And the king stood on the dais, and made a covenant before Jehovah, to walk after Jehovah, and to keep his commandments and his testimonies and his statutes with all [his] heart, and with all [his] soul, to establish the words of this covenant that are written in this book. And all the people stood to the covenant.
Matthew Henry's Commentary on 2 Kings 23:3
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.
