To burn human bones was contrary to all the ordinary Jewish feelings with respect to the sanctity of the sepulchre, and had even been denounced as a sin of a heinous character when committed by a king of Moab Amos 2:1. Joshua did it, because justified by the divine command (marginal reference).

And as Josiah turned himself - This verse is much more complete in the Septuagint, and in the Hexaplar Syriac version at Paris. I shall give the whole, making a distinction where, in those versions, any thing is added: "And as Josiah turned himself, he spied the sepulchres that were there in the mount, and sent and took the bones out of the sepulchres, and burnt them upon the altar, and polluted it: according to the word of the Lord which the man of God proclaimed [when Jeroboam stood by the altar at the feast. And turning about, he cast his eyes on the sepulcher of the man of God] who proclaimed these words." See 1 Kings 13:2 (note), where these things were predicted, and see the notes there.

And as Josiah turned himself,.... From the high place, and the altar at Bethel; for he not only gave orders for the destroying of idolatrous places and idols, but he saw them executed himself:

he spied the sepulchres that were there in the mount; the graves of idolatrous priests and worshippers, who chose to be buried near those places of idolatry; nor was it unusual for persons to be buried on hills and mountains, see Joshua 24:30 and this was a custom in other nations formerly (t), particularly among the Indians (u) now, who in many things agree with the Jews:

and sent and took the bones out of the sepulchres, and burnt them upon the altar; where they had sacrificed to idols:

and polluted it; with their bones, which, according to the law, were defiling, and which was done in contempt of their idolatrous worship there:

according to the word of the Lord which the man of God proclaimed, who proclaimed these words; or things; foretold that such a king by name would arise, and burn men's bones upon the altar, and which had been foretold more than three hundred and fifty years before this time.

In order to desecrate this idolatrous site for all time, Josiah had human bones taken out of the graves that were to be found upon the mountain, and burned upon the altar, whereby the prophecy uttered in the reign of Jeroboam by the prophet who came out of Judah concerning this idolatrous place of worship was fulfilled; but he spared the tomb of that prophet himself (cf. 1 Kings 13:26-32). The mountain upon which Josiah saw the graves was a mountain at Bethel, which was visible from the bamah destroyed. ציּוּן, a sepulchral monument, probably a stone erected upon the grave. וימלּטוּ: "so they rescued (from burning) his bones (the bones of the prophet who had come from Judah), together with the bones of the prophet who had come from Samaria," i.e., of the old prophet who sprang from the kingdom of the ten tribes and had come to Bethel (1 Kings 13:11). משּׁמרון בּא in antithesis to מיהוּדה ot sisehtit בּא denotes simply descent from the land of Samaria.

(Note: 2 Kings 23:16-18 are neither an interpolation of the editor, i.e., of the author of our books of Kings (Staehelin), nor an interpolation from a supplement to the account in 1 Kings 13:1-32 (Thenius). The correspondence between the וגם in 2 Kings 23:15 and the וגם in 2 Kings 23:18 does not require this assumption; and the pretended discrepancy, that after Josiah had already reduced the altar to ruins (2 Kings 23:15) he could not possibly defile it by burning human bones upon it (2 Kings 23:16), is removed by the very natural solution, that המזבח in 2 Kings 23:16 does not mean the altar itself, but the site of the altar that had been destroyed.)

And as Josiah turned himself, he spied the sepulchres that were there in the mount, and sent, and took the bones out of the sepulchres, and burned them upon the altar, and polluted it, according to the word of the LORD which the {o} man of God proclaimed, who proclaimed these words.

(o) According to the prophecy of Iddo, 1Ki 13:2.

23:16 Himself - Josiah's care and zeal was so great, that he would not trust his officers with these things, but would see them done with his own eyes. These words - Three hundred years before it was done.

16. according to the word of the Lord which the man of God proclaimed, &c.-In carrying on these proceedings, Josiah was prompted by his own intense hatred of idolatry. But it is remarkable that this act was predicted three hundred twenty-six years before his birth, and his name also was expressly mentioned, as well as the very place where it should be done (1Ki 13:2). This is one of the most most remarkable prophecies in the Bible.

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.
