Concerning Josiah we are here told,

I.That he was very young when he began to reign (Kg2 22:1), only eight years old. Solomon says, Woe unto thee, O land! when thy king is a child; but happy art thou, O land! when thy king is such a child. Our English Israel had once a king that was such a child, Edward VI. Josiah, being young, had not received any bad impressions from the example of his father and grandfather, but soon saw their errors, and God gave his grace to take warning by them. See Eze 18:14, etc.

II.That he did that which was right in the sight of the Lord, Kg2 22:2. See the sovereignty of divine grace - the father passed by and left to perish in his sin, the son a chosen vessel. See the triumphs of that grace - Josiah born of a wicked father, no good education nor good example given him, but many about him who no doubt advised him to tread in his father's steps and few that gave him any good counsel, and yet the grace of God made him an eminent saint, cut him off from the wild olive and grafted him into the good olive, Rom 11:24. Nothing is too hard for that grace to do. He walked in a good way, and turned not aside (as some of his predecessors had done who began well) to the right hand nor to the left. There are errors on both hands, but God kept him in the right way; he fell neither into superstition nor profaneness.

III.That he took care for the repair of the temple. This he did in the eighteenth year of his reign, Kg2 22:3. Compare Ch2 34:8. He began much sooner to seek the Lord (as appears, Ch2 34:3), but it is to be feared the work of reformation went slowly on and met with much opposition, so that he could not effect what he desired and designed, till his power was thoroughly confirmed. The consideration of the time we unavoidably lost in our minority should quicken us, when we have come to years, to act with so much the more vigour in the service of God. Having begun late we have need work hard. He sent Shaphan, the secretary of state, to Hilkiah the high priest, to take an account of the money that was collected for this use by the door-keepers (Kg2 22:4); for, it seems, they took much the same way of raising the money that Joash took, Kg2 12:9. When people gave by a little at a time the burden was insensible, and, the contribution being voluntary, it was not complained of. This money, so collected, he ordered him to lay out for the repair of the temple, Kg2 22:5, Kg2 22:6. And now, it seems, the workmen (as in the days of Joash) acquitted themselves so well that there was no reckoning made with them (Kg2 22:7), which is certainly mentioned to the praise of the workmen, that they gained such a reputation for honesty, but whether to the praise of those that employed them I know not; a man should count money (we say) after his own father; it would not have been amiss to have reckoned with the workmen, that others also might be satisfied of their honesty.

IV.That, in repairing the temple, the book of the law was happily found and brought to the king, Kg2 22:8, Kg2 22:10. Some think this book was the autograph, or original manuscript, of the five books of Moses, under his own hand; others think it was only an ancient and authentic copy. Most likely it was that which, by the command of Moses, was laid up in the most holy place, Deu 31:24, etc. 1. It seems, this book of the law was lost or missing. Perhaps it was carelessly mislaid and neglected, thrown by into a corner (as some throw their Bibles), by those that knew not the value of it, and forgotten there; or it was maliciously concealed by some of the idolatrous kings, or their agents, who were restrained by the providence of God or their own consciences from burning and destroying it, but buried it, in hopes it would never see the light again; or, as some think, it was carefully laid up by some of its friends, lest it should fall into the hands of its enemies. Whoever were the instruments of its preservation, we ought to acknowledge the hand of God in it. If this was the only authentic copy of the Pentateuch then in being, which had (as I may say) so narrow a turn for its life and was so near perishing, I wonder the hearts of all good people did not tremble for that sacred treasure, as Eli's for the ark, and I am sure we now have reason to thank God, upon our knees, for that happy providence by which Hilkiah found this book at this time, found it when he sought it not, Isa 65:1. If the holy scriptures had not been of God, they would not have been in being at this day; God's care of the Bible is a plain indication of his interest in it. 2. Whether this was the only authentic copy in being or no, it seems the things contained in it were new both to the king himself and to the high priest; for the king, upon the reading of it, rent his clothes. We have reason to think that neither the command for the king's writing a copy of the law, nor that for the public reading of the law every seventh year (Deu 17:18; Deu 31:10, Deu 31:11), had been observed for a long time; and when the instituted means of keeping up religion are neglected religion itself will soon go to decay. Yet, on the other hand, if the book of the law was lost, it seems difficult to determine what rule Josiah went by in doing that which was right in the sight of the Lord, and how the priests and people kept up the rites of their religion. I am apt to think that the people generally took up with abstracts of the law, like our abridgements of the statutes, which the priests, to save themselves the trouble of writing and the people of reading the book at large, had furnished them with - a sort of ritual, directing them in the observances of their religion, but leaving out what they thought fit, and particularly the promises and threatenings (Lev. 26 and Deu. 28, etc.), for I observe that these were the portions of the law which Josiah was so much affected with (Kg2 22:13), for these were new to him. No summaries, extracts, or collections, out of the Bible (though they may have their use) can be effectual to convey and preserve the knowledge of God and his will like the Bible itself. It was no marvel that the people were so corrupt when the book of the law was such a scarce thing among them; where that vision is not the people perish. Those that endeavoured to debauch them no doubt used all the arts they could to get that book out of their hands. The church of Rome could not keep up the use of images but by forbidding the use of the scripture. 3. It was a great instance of God's favour, and a token for good to Josiah and his people, that the book of the law was thus seasonably brought to light, to direct and quicken that blessed reformation which Josiah had begun. It is a sign that God has mercy in store for a people when he magnifies his law among them and makes that honourable, and furnishes them with means for the increase of scripture-knowledge. The translating of the scriptures into vulgar tongues was the glory, strength, and joy of the Reformation from Popery. It is observable that they were about a good work, repairing the temple, when they found the book of the law. Those that do their duty according to their knowledge shall have their knowledge increased. To him that hath shall be given. The book of the law was an abundant recompence for all their care and cost about the repair of the temple. 4. Hilkiah the priest was exceedingly well pleased with the discovery. "O," says he to Shaphan, "rejoice with me, for I have found the book of the law, heurēka, heurēka, - I have found, I have found, that jewel of inestimable value. Here, carry it to the king; it is the richest jewel of his crown. Read it before him. He walks in the way of David his father, and, if he be like him, he will love the book of the law and bid that welcome; that will be his delight and his counsellor."

I have found the book of the law - Was this the autograph of Moses? It is very probable that it was, for in the parallel place; Ch2 34:14, it is said to be the book of the law of the Lord by Moses. It is supposed to be that part of Deuteronomy (28, 29, 30, and 31), which contains the renewing of the covenant in the plains of Moab, and which contains the most terrible invectives against the corrupters of God's word and worship.

The rabbins say that Ahaz, Manasseh, and Amon endeavored to destroy all the copies of the law, and this only was saved by having been buried under a paving-stone. It is scarcely reasonable to suppose that this was the only copy of the law that was found in Judea; for even if we grant that Ahaz, Manasseh, and Amon had endeavored to destroy all the books of the law, yet they could not have succeeded so as to destroy the whole. Besides, Manasseh endeavored after his conversion to restore every part of the Divine worship, and in this he could have done nothing without the Pentateuch; and the succeeding reign of Amon was too short to give him opportunity to undo every thing that his penitent father had reformed. Add to all these considerations, that in the time of Jehoshaphat teaching from the law was universal in the land, for he set on foot an itinerant ministry, in order to instruct the people fully: for "he sent to his princes to teach in the cities of Judah; and with them he sent Levites and priests; and they went about through all the cities of Judah, and taught the people, having the book of the Lord with them;" see Ch2 17:7-9. And if there be any thing wanting to show the improbability of the thing, it must be this, that the transactions mentioned here took place in the eighteenth year of the reign of Josiah, who had, from the time he came to the throne, employed himself in the restoration of the pure worship of God; and it is not likely that during these eighteen years he was without a copy of the Pentateuch. The simple fact seems to be this, that this was the original of the covenant renewed by Moses with the people in the plains of Moab, and which he ordered to be laid up beside the ark; (Deu 31:26); and now being unexpectedly found, its antiquity, the occasion of its being made, the present circumstances of the people, the imperfect state in which the reformation was as yet, after all that had been done, would all concur to produce the effect here mentioned on the mind of the pious Josiah.

And Hilkiah the high priest said unto Shaphan the scribe,.... Not at the first time of his message to him, but afterwards that he attended on him upon the same business; after the high priest had examined the temple to know what repairs it wanted, and where:

I have found the book of the law in the house of the Lord; some think this was only the book of Deuteronomy, and some only some part of that; rather the whole Pentateuch, and that not a copy of it, but the very autograph of Moses, written with his own hand, as it seems from Ch2 34:14. Some say he found it in the holy of holies, on the side of the ark; there it was put originally; but, indeed, had it been there, he might have found it before, and must have seen it, since, as high priest, he entered there once every year; more probably some pious predecessor of his had taken it from thence in a time of general corruption, as in the reign of Manasseh, and hid it in some private place, under a lay of stones, as Jarchi, in some hole in the wall, which upon search about repairs was found there:

and Hilkiah gave the book to Shaphan, and he read it; and though there might be some copies of it in private hands, yet scarce; and perhaps Shaphan had never seen one, at least a perfect one, or however had never read it through, as now he did.

HILKIAH FINDS THE BOOK OF THE LAW. (Kg2 22:8-15)

Hilkiah said . . . I have found the book of the law in the house of the Lord, &c.--that is, the law of Moses, the Pentateuch. It was the temple copy which, had been laid (Deu 31:25-26) beside the ark in the most holy place. During the ungodly reigns of Manasseh and Amon--or perhaps under Ahaz, when the temple itself had been profaned by idols, and the ark also (Ch2 35:3) removed from its site; it was somehow lost, and was now found again during the repair of the temple [KEIL]. Delivered by Hilkiah the discoverer to Shaphan the scribe [Kg2 22:8], it was by the latter shown and read to the king. It is thought, with great probability, that the passage read to the king, and by which the royal mind was so greatly excited, was a portion of Deuteronomy, the twenty-eighth, twenty-ninth, and thirtieth chapters, in which is recorded a renewal of the national covenant, and an enumeration of the terrible threats and curses denounced against all who violated the law, whether prince or people. The impressions of grief and terror which the reading produced on the mind of Josiah have seemed to many unaccountable. But, as it is certain from the extensive and familiar knowledge displayed by the prophets, that there were numbers of other copies in popular circulation, the king must have known its sacred contents in some degree. But he might have been a stranger to the passage read him, or the reading of it might, in the peculiar circumstances, have found a way to his heart in a manner that he never felt before. His strong faith in the divine word, and his painful consciousness that the woeful and long-continued apostasies of the nation had exposed them to the infliction of the judgments denounced, must have come with overwhelming force on the heart of so pious a prince.
