2 Kings 23:1 - 8

23:1 ¶ And the king sent, and they gathered unto him all the elders of Judah and of Jerusalem.
23:2 And the king went up into the house of the LORD, and all the men of Judah and all the inhabitants of Jerusalem with him, and the priests, and the prophets, and all the people, both small and great: and he read in their ears all the words of the book of the covenant which was found in the house of the LORD.
23:3 And the king stood by a pillar, and made a covenant before the LORD, to walk after the LORD, and to keep his commandments and his testimonies and his statutes with all their heart and all their soul, to perform the words of this covenant that were written in this book. And all the people stood to the covenant.
23:4 ¶ And the king commanded Hilkiah the high priest, and the priests of the second order, and the keepers of the door, to bring forth out of the temple of the LORD all the vessels that were made for Baal, and for the grove, and for all the host of heaven: and he burned them without Jerusalem in the fields of Kidron, and carried the ashes of them unto Bethel.
23:5 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.
23:6 And he brought out the grove from the house of the LORD, without Jerusalem, unto the brook Kidron, and burned it at the brook Kidron, and stamped it small to powder, and cast the powder thereof upon the graves of the children of the people.
23:7 And he brake down the houses of the sodomites, that were by the house of the LORD, where the women wove hangings for the grove.
23:8 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 Beersheba, and brake down the high places of the gates that were in the entering in of the gate of Joshua the governor of the city, which were on a man's left hand at the gate of the city.

2 Kings 23:21 - 24

23:21 And the king commanded all the people, saying, Keep the passover unto the LORD your God, as it is written in the book of this covenant.
23:22 Surely there was not holden such a passover from the days of the judges that judged Israel, nor in all the days of the kings of Israel, nor of the kings of Judah;
23:23 But in the eighteenth year of king Josiah, wherein this passover was holden to the LORD in Jerusalem.
23:24 Moreover the workers with familiar spirits, and the wizards, and the images, and the idols, and all the abominations that were spied in the land of Judah and in Jerusalem, did Josiah put away, that he might perform the words of the law which were written in the book that Hilkiah the priest found in the house of the LORD.
