5 And he put down the idolatrous priests, whom the kings of Judah had ordained to burn incense in the high places in the cities of Judah, and in the places round about Jerusalem; them also that burned incense unto Baal, to the sun, and to the moon, and to the planets, and to all the host of heaven. 6 And he brought out the Asherah from the house of Jehovah, without Jerusalem, unto the brook Kidron, and burned it at the brook Kidron, and beat it to dust, and cast the dust thereof upon the graves of the common people. 7 And he brake down the houses of the sodomites, that were in the house of Jehovah, where the women wove hangings for the Asherah. 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 brake 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 a man's left hand at the gate of the city. 9 Nevertheless the priests of the high places came not up to the altar of Jehovah in Jerusalem, but they did eat 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.
