II Chronicles 34:5

And he burnt the bones of the priests upon their altars, i.e., he caused the bones of the idolatrous priests to be taken from their graves and burnt on the spot where the destroyed altars had stood, that he might defile the place with the ashes of the dead. In these words is summarized what is stated in Kg2 23:13 and Kg2 23:14 as to the defilement of the places of sacrifice built upon the Mount of Olives by the bones of the dead, and in Kg2 23:16-20 as to the burning of the bones of the high priests of Bethel, after they had been taken from their graves, upon their own altars. מזבחותים is an orthographical error for מזבּחותם.

Before we see Judah and Jerusalem ruined we shall yet see some glorious years, while good Josiah sits at the helm. By his pious endeavours for reformation God tried them yet once more; if they had known in this their day, the day of their visitation, the things that belonged to their peace and improved them, their ruin might have been prevented. But after this reign they were hidden from their eyes, and the next reigns brought an utter desolation upon them. In this chapter we have, I. A general account of Josiah's character (Ch2 34:1, Ch2 34:2). II. His zeal to root out idolatry (Ch2 34:3-7). III. His care to repair the temple (Ch2 34:8-13). IV. The finding of the book of the law and the good use made of it (Ch2 34:14-28). V. The public reading of the law to the people and their renewing their covenant with God thereupon (Ch2 34:29-33). Much of this we had 2 Kings 22.
