Concerning Josiah we are here told, 1. That he came to the crown when he was very young, only eight years old (yet his infancy did not debar him from his right), and he reigned thirty-one years (Ch2 34:1), a considerable time. I fear, however, that in the beginning of his reign things went much as they had done in his father's time, because, being a child, he must have left the management of them to others; so that it was not till his twelfth year, which goes far in the number of his years, that the reformation began, Ch2 34:3. He could not, as Hezekiah did, fall about it immediately. 2. That he reigned very well (Ch2 34:2), approved himself to God, trod in the steps of David, and did not decline either to the right hand of to the left: for there are errors on both hands. 3. That while he was young, about sixteen years old, he began to seek after God, Ch2 34:3. We have reason to think he had not so good an education as Manasseh had (it is well if those about him did not endeavour to corrupt and debauch him); yet he thus sought God when he was young. It is the duty and interest of young people, and will particularly be the honour of young gentlemen, as soon as they come to years of understanding, to begin to seek God; for those that seek him early shall find him. 4. That in the twelfth year of his reign, when it is probable he took the administration of the government entirely into his own hands, he began to purge his kingdom from the remains of idolatry; he destroyed the high places, groves, images, altars, all the utensils of idolatry, v. 3, 4. He not only cast them out as Manasseh did, but broke them to pieces, and made dust of them. This destruction of idolatry is here said to be in his twelfth year, but it was said (Kg2 23:23) to be in his eighteenth year. Something was probably done towards it in his twelfth year; then he began to purge out idolatry, but that good work met with opposition, so that it was not thoroughly done till they had found the book of the law six years afterwards. But here the whole work is laid together briefly which was much more largely and particularly related in the Kings. His zeal carried him out to do this, not only in Judah and Jerusalem, but in the cities of Israel too, as far as he had any influence upon them.

The cities of Manasseh - Even those who were under the government of the Israelitish king permitted their idols and places of idolatry to be hewn down and destroyed: after the truth was declared and acknowledged, the spade and the axe were employed to complete the reformation.

Now in the eighteenth year of his reign, when he had purged the land and the house,.... The temple; this was in the twenty sixth year of his age, six years this work had been doing before it was finished:

he sent Shaphan the son of Azaliah: who only is mentioned in Kg2 22:3 two more are added here, as follow:

and Maaseiah the governor of the city; the city of Jerusalem, a deputy governor under the king, a sort of mayor or provost:

and Joah the son of Joahaz the recorder; who was over the book of memorials, as the Targum; the word may be rendered "the remembrances"; and, according to Jarchi, as every king of Judah had a scribe to write down the memorable things that happened in his reign, good or bad, so the scribe had one by him, to put him in mind of every transaction, from whom he wrote it down:

to repair the house of the Lord his God; that is, to give orders for the doing of it, to prepare for it, provide workmen, and appoint overseers of them: it had not been repaired since the times of Joash, which, according to the Jewish chronology (y), was a space of two hundred and eighteen years.

with their mattocks--or, "in their deserts"--so that the verse will stand thus: "And so did [namely, break the altars and burn the bones of priests] he in the cities of Manasseh, and Ephraim, and Simeon, even unto Naphtali, in their deserted suburbs." The reader is apt to be surprised on finding that Josiah, whose hereditary possessions were confined to the kingdom of Judah, exercised as much authority among the tribes of Ephraim, Manasseh, Simeon, and others as far as Naphtali, as he did within his own dominion. Therefore, it is necessary to observe that, after the destruction of Samaria by Shalmaneser, the remnant that continued on the mountains of Israel maintained a close intercourse with Judah, and looked to the sovereigns of that kingdom as their natural protectors. Those kings acquired great influence over them, which Josiah exercised in removing every vestige of idolatry from the land. He could not have done this without the acquiescence of the people in the propriety of this proceeding, conscious that this was conformable to their ancient laws and institutions. The Assyrian kings, who were now masters of the country, might have been displeased at the liberties Josiah took beyond his own territories. But either they were not informed of his doings, or they did not trouble themselves about his religious proceedings, relating, as they would think, to the god of the land, especially as he did not attempt to seize upon any place or to disturb the allegiance of the people [CALMET].
