The cities of Samaria - The reformation which Josiah effected in Samaria, is narrated in Chronicles. It implies sovereignty to the furthest northern limits of Galilee, and is explained by the general political history of the East during his reign. Between 632-626 B.C. the Scythians ravaged the more northern countries of Armenia, Media, and Cappadocia, and found their way across Mesopotamia to Syria, and thence, made an attempt to invade Egypt. As they were neither the fated enemy of Judah, nor had any hand in bringing that enemy into the country, no mention is made of them in the Historical Books of Scripture. It is only in the prophets that we catch glimpses of the fearful sufferings of the time Zephaniah 2:4-6; Jeremiah 1:13-15; Jeremiah 6:2-5; Ezekiel 38; 39. The invasion had scarcely gone by, and matters settled into their former position, when the astounding intelligence must have reached Jerusalem that the Assyrian monarchy had fallen; that Nineveh was destroyed, and that her place was to be taken, so far as Syria and Palestine were concerned, by Babylon. This event is fixed about 625 B.C., which seems to be exactly the time during which Josiah was occupied in carrying out his reformation in Samaria. The confusion arising in these provinces from the Scythian invasion and the troubles in Assyria was taken advantage of by Josiah to enlarge his own sovereignty. There is every indication that Josiah did, in fact, unite under his rule all the old "land of Israel" except the trans-Jordanic region, and regarded himself as subject to Nabopolassar of Babylon.

That were in the cities of Samaria - Israel had now no king; and Josiah, of the blood royal of Judah, had certainly a direct right to the kingdom; he had, at this time, an especial commission from God, to reform every abuse through the whole land - all that ground that was given by the Lord as an inheritance to the twelve sons of Jacob. Therefore he had every right to carry his plans of reformation into the Samaritan states.

And all the houses also of the high places,.... The temples of the idols there, and the houses for the priests to dwell in:

that were in the cities of Samaria, which the kings of Israel had made to provoke the Lord to anger, Josiah took away; particularly in the cities of Manasseh, Ephraim, and Simeon, unto Naphtali, 2 Chronicles 34:6 the Israelites that remained there acknowledging Josiah as their king; and perhaps, after the defeat of Sennacherib, many of the cities of Israel might put themselves under the protection of Hezekiah, and especially upon the destruction of the Assyrian empire; and Manasseh, with his liberty, might have his kingdom enlarged by the king of Babylon; and which being continued and increased in the times of Josiah, might be the reason of his opposing the king of Egypt in favour of the king of Babylon:

and did to them according to all the acts that he had done in Bethel; defiled them, and broke down the altars in them.

All the houses of the high places that were in the (other) cities of Samaria Josiah also destroyed in the same way as that at Bethel, and offered up the priests of the high places upon the altars, i.e., slew them upon the altars on which they had offered sacrifice, and burned men's bones upon them (the altars) to defile them. The severity of the procedure towards these priests of the high places, as contrasted with the manner in which the priests of the high places in Judah were treated (2 Kings 23:8 and 2 Kings 23:9), may be explained partly from the fact that the Israelitish priests of the high places were not Levitical priests, but chiefly from the fact that they were really idolatrous priests.

And all the houses also of the high places that were in the cities of Samaria, which the kings of Israel had made to provoke the Lord to anger, Josiah took away, and did to them according to all the acts that he had done in Bethel.

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.
