5 And he deposed the idolatrous priests whom the kings of Judah had ordained to burn incense in the high places at the cities of Judah and round about Jerusalem; those also who burned incense to Ba'al, to the sun, and the moon, and the constellations, and all the host of the heavens. 6 And he brought out the Ashe'rah from the house of the Lord, outside Jerusalem, to the brook Kidron, and burned it at the brook Kidron, and beat it to dust and cast the dust of it upon the graves of the common people. 7 And he broke down the houses of the male cult prostitutes which were in the house of the Lord, where the women wove hangings for the Ashe'rah. 8 And he brought all the priests out of the cities of Judah, and defiled the high places where the priests had burned incense, from Geba to Beer-sheba; and he broke down the high places of the gates that were at the entrance of the gate of Joshua the governor of the city, which were on one's left at the gate of the city. 9 However, the priests of the high places did not come up to the altar of the Lord in Jerusalem, but they ate unleavened bread among their brethren.

(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.
