4 Then the king instructed Hilkiah the high priest and the priests of the second rank and the Temple gatekeepers to remove from the Lord 's Temple all the articles that were used to worship Baal, Asherah, and all the powers of the heavens. The king had all these things burned outside Jerusalem on the terraces of the Kidron Valley, and he carried the ashes away to Bethel. 5 He did away with the idolatrous priests, who had been appointed by the previous kings of Judah, for they had offered sacrifices at the pagan shrines throughout Judah and even in the vicinity of Jerusalem. They had also offered sacrifices to Baal, and to the sun, the moon, the constellations, and to all the powers of the heavens. 6 The king removed the Asherah pole from the Lord 's Temple and took it outside Jerusalem to the Kidron Valley, where he burned it. Then he ground the ashes of the pole to dust and threw the dust over the graves of the people.

Commentary on 2 Kings 23:4-14
(Read 2 Kings 23:4-14)
What abundance of wickedness in Judah and Jerusalem! One would not have believed it possible, that in Judah, where God was known, in Israel, where his name was great, in Salem, in Zion, where his dwelling-place was, such abominations should be found. Josiah had reigned eighteen years, and had himself set the people a good example, and kept up religion according to the Divine law; yet, when he came to search for idolatry, the depth and extent were very great. Both common history, and the records of God's word, teach, that all the real godliness or goodness ever found on earth, is derived from the new-creating Spirit of Jesus Christ.
