'Discovery' in the Bible

Then Hilkiah, the chief priest, said to Shaphan the scribe, I have made discovery of the book of the law in the house of the Lord. So Hilkiah gave it to Shaphan;

And all those who had control of spirits, and the wonder-workers, and the images, and the false gods, and all the disgusting things which were seen in the land of Judah and in Jerusalem, Josiah put away, so that he might give effect to the words of the agreement recorded in the book which Hilkiah the priest made discovery of in the house of the Lord.
