One of the reforms of King Josiah was that he defiled Topheth in the valley of the sons of Hinnom. Topheth was a place where people would sacrifice their children to the pagan god Molech, and it was considered an abomination in the eyes of God. King Josiah ordered that the place be defiled, and it was turned into a garbage dump to show that it was a place of shame and disgust. This reform was one of many that Josiah implemented to rid the kingdom of Judah of pagan worship and restore the worship of the one true God.
