2 kings 22-24

During the reign of Josiah the temple to God Yahweh was not the only thing still standing in Jerusalem that king Solomon had built. There was a high place east of the city to the Sidonite idol Astarte still standing. Josiah could have followed the example of all the kings before his and not touched this shrine. But he chose to bring it down. In his devotion to God Josiah would let nothing stand in his was of honoring the one true God os Israel.
