he promise which the Lord made to Josiah, as stated in `2 Kings 22:20`, was because of the splendid work of reformation which the king had inaugurated and was prosecuting against the false and idolatrous religious systems that had become established in the land, during the preceding reigns of the kings of Judah. While it is not specifically stated that this promise was conditioned on Josiah's continued faith and obedience to the Lord, yet we can be assured that such must have been the case, for all of God's promises are of this nature. As Josiah did not die in peace, but was slain in battle, we would naturally be led to examine the Scriptures to find wherein Josiah had acted contrary to the Lord's will. The incidents narrated in the next chapter, are described more in detail in `2 Chronicles 35th` chapter and the reason why Josiah suffered a violent death is clearly outlined in the 20th verse. What a lesson far all–to mind their own business and not to meddle in the affairs of others!
