2 Kings 23:4-6, 10, 14

Then the king commanded Hilkiah the high priest and the priests of the second rank and the doorkeepers to bring out of the temple of the LORD all the articles made for Baal, for [the goddess] Asherah, and for all the [starry] host of heaven; and he burned them outside Jerusalem in the fields of the Kidron, and carried their ashes to Bethel [where Israel’s idolatry began]. [1 Kin 12:28, 29] He got rid of the idolatrous priests whom the kings of Judah had ordained to burn incense [to pagan gods] in the high places in Judah’s cities and all around Jerusalem—also those who burned incense to Baal, to the sun, to the moon, to the constellations [of the zodiac], and to all the [starry] host of heaven. Josiah brought out the Asherah from the house of the LORD to the Brook Kidron outside Jerusalem, and burned it there, and ground it to dust, and threw its dust on the graves of the common people [who had sacrificed to it].

Josiah also defiled Topheth, which is in the Valley of Ben-hinnom (son of Hinnom), so that no man could make his son or his daughter pass through the fire [as a burnt offering] for Molech. [Ezek 16:21]

He broke in pieces the sacred pillars (cultic memorial stones, images) and cut down the Asherim and replaced them with human bones [to desecrate the places forever].
