20 Josiah slaughtered all the priests of those high places on the altars and burned human bones on them. Then he went back to Jerusalem.
20 And he sacrificed all the priests of the high places who were there, on the altars, and burned human bones on them. Then he returned to Jerusalem.
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.
20 He executed all the priests of the high places who were there, on the altars, and burned men's bones on them; and he returned to Jerusalem.
20 He executed the priests of the pagan shrines on their own altars, and he burned human bones on the altars to desecrate them. Finally, he returned to Jerusalem.

Commentary on 2 Kings 23:15-24
(Read 2 Kings 23:15-24)
Josiah's zeal extended to the cities of Israel within his reach. He carefully preserved the sepulchre of that man of God, who came from Judah to foretell the throwing down of Jeroboam's altar. When they had cleared the country of the old leaven of idolatry, then they applied themselves to the keeping of the feast. There was not holden such a passover in any of the foregoing reigns. The revival of a long-neglected ordinance, filled them with holy joy; and God recompensed their zeal in destroying idolatry with uncommon tokens of his presence and favour. We have reason to think that during the remainder of Josiah's reign, religion flourished.
