The king went up to the house of the Lord, and with him all the men of Judah and all the inhabitants of Jerusalem, the priests, the prophets, and all the people, both small and great; and he read in their hearing all the words of the book of the covenant which was found in the house (temple) of the Lord.

Then the king commanded all the people, saying, “Celebrate the Passover to the Lord your God as it is written in this book of the covenant.”

And the king went up to the house of the Lord with all the men of Judah, the inhabitants of Jerusalem, the priests, the Levites, and all the people, from the greatest to the least; and he read aloud so they could hear all the words of the Book of the Covenant which was found in the house of the Lord.
