After the high priest, Hilkiah, re-discovered the Book of the Law in the Temple in Jerusalem in the eighteenth year of Josiah’s reign (in 624BC), King Josiah called the elders of Judah together to renew their covenant with the LORD. All the articles associated with Baal and Asherah worship were removed from the Temple and burned in the Kidron Valley outside the city.
Josiah tore down the quarters of the male shrine-prostitutes and destroyed Topheth (‘the fireplace’) – the pagan worship site in the Valley of Hinnom (the ‘Valley of wickedness’) – where children were sacrificed to the god Molech. He removed the statues of the horses and chariots dedicated to the Egyptian Sun god Re at the entrance to the Temple in Jerusalem, and destroyed the altars to the pagan gods Ashtoreth, Chemosh and Molech on the Hill of Corruption (the Mount of Olives).
The people of Jerusalem then celebrated the Passover festival for the first time in many generations and renewed their commitment to the LORD.
