2 Kings 23:20 Meaning and Commentary

2 Kings 23:20

And he slew all the priests of the high places that were
there
The idolatrous priests who sacrificed to Baal, and other Heathen deities; for as for others that burnt incense in high places, yet to the true God, those he spared, though they were not suffered to officiate at the altar of God: the others he slew

upon the altars;
where they sacrificed:

and burnt men's bones upon them:
the bones of the priests, and worshippers of idols, as he had done at Bethel:

and returned to Jerusalem;
after he had gone through the land, both of Judah and Israel, and abolished idolatrous worship everywhere.

2 Kings 23:20 In-Context

18 Josiah said, "Don't trouble his bones." So they left his bones undisturbed, along with the bones of the prophet from Samaria.

19 But Josiah hadn't finished. He now moved through all the towns of Samaria where the kings of Israel had built neighborhood sex-and-religion shrines, shrines that had so angered God. He tore the shrines down and left them in ruins - just as at Bethel

20 He killed all the priests who had conducted the sacrifices and cremated them on their own altars, thus desacralizing the altars. Only then did Josiah return to Jerusalem.

21 The king now commanded the people, "Celebrate the Passover to God, your God, exactly as directed in this Book of the Covenant.

22 This commanded Passover had not been celebrated since the days that the judges judged Israel - none of the kings of Israel and Judah had celebrated it.
