And when they brought out the money that was brought into the house of the LORD, Hilkiah the priest found a book of the law of the LORD given by Moses.

And Hilkiah answered and said to Shaphan the scribe, I have found the book of the law in the house of the LORD. And Hilkiah delivered the book to Shaphan.
