2 Chronicles 34:19-21; 2 Chronicles 34:29-33
When the king heard what was written in the book, God's Revelation, he ripped his robes in dismay.
And then he called for Hilkiah, Ahikam son of Shaphan, Abdon son of Micah, Shaphan the royal secretary, and Asaiah the king's personal aide.
He ordered them all: "Go and pray to God for me and what's left of Israel and Judah. Find out what we must do in response to what is written in this book that has just been found! God's anger must be burning furiously against us - our ancestors haven't obeyed a thing written in this book of God, followed none of the instructions directed to us."
The king acted immediately, assembling all the elders of Judah and Jerusalem,
and then proceeding to The Temple of God bringing everyone in his train - priests and prophets and people ranging from the least to the greatest. Then he read out publicly everything written in the Book of the Covenant that was found in The Temple of God.
The king stood by his pillar and before God solemnly committed himself to the covenant: to follow God believingly and obediently; to follow his instructions, heart and soul, on what to believe and do; to confirm with his life the entire covenant, all that was written in the book.
Then he made everyone in Jerusalem and Benjamin commit themselves. And they did it. They committed themselves to the covenant of God, the God of their ancestors.
Josiah did a thorough job of cleaning up the pollution that had spread throughout Israelite territory and got everyone started fresh again, serving and worshiping their God. All through Josiah's life the people kept to the straight and narrow, obediently following God, the God of their ancestors.
