| Barnes' Notes on the Bible This chapter is parallel with 2 Kings 12, but treats the matters common to both narratives in a different and, apparently, supplemental way.
Clarke's Commentary on the BibleJoash was seven years old - As he was hidden six years in the temple, and was but seven when he came to the throne, he could have been but one year old when he was secreted by his aunt; see on 2 Chronicles 22:10 (note).
Gill's Exposition of the Entire BibleJoash was seven years old when he began to reign,.... This, and the following verse, are the same with 2 Kings 11:21. See Gill on 2 Kings 12:1. See Gill on 2 Kings 12:2.
Keil and Delitzsch Biblical Commentary on the Old TestamentThe reign of Joash; cf. 2 Kings 12. - In both accounts only two main events in Joash's reign of forty years are narrated at any length, - the repair of the temple, and the campaign of the Syrian king Hazael against Jerusalem. Besides this, at the beginning, we have a statement as to the duration and spirit of his reign; and in conclusion, the murder of Joash in consequence of a conspiracy is mentioned. Both accounts agree in all essential points, but are shown to be extracts containing the most important part of a more complete history of Joash, by the fact that, on the one hand, in 2 Kings 12 single circumstances are communicated in a more detailed and more exact form than that in which the Chronicle states them; while, on the other hand, the account of the Chronicle supplements the account in 2 Kings 12 in many respects. To these latter belong the account of the marriage of Joash, and his many children, the account of the death of Jehoiada at the age of 130 years, and his honourable burial with the kings, etc.; see on 2 Chronicles 24:15.

Jamieson-Fausset-Brown Bible CommentaryCHAPTER 24 2Ch 24:1-14. Joash Reigns Well All the Days of Jehoiada. 1-3. Joash . began to reign-(See on [450]2Ki 12:1-3).
Matthew Henry's Concise Commentary24:1-14 Joash is more zealous about the repair of the temple than Jehoiada himself. It is easier to build temples, than to be temples to God. But the repairing of places for public worship is a good work, which all should promote. And many a good work would be done that now lies undone, if active men would put it forward.
Matthew Henry's Whole Bible CommentaryChapter 24 We have here the history of the reign of Joash, the progress of which, and especially its termination, were not of a piece with its beginning, nor shone with so much lustre. How wonderfully he was preserved for the throne, and placed in it, we read before; now here we are told how he began in the spirit, but ended in the flesh. I. In the beginning of his time, while Jehoiada lived, he did well; particularly, he took care to put the temple in good repair (v. 1-14). II. In the latter end of his time, after Jehoiada's death, he apostatized from God, and his apostasy was his ruin. 1. He set up the worship of Baal again (v. 15-18), though warned to the contrary (v. 19). 2. He put Zechariah the prophet to death because he reproved him for what he had done (v. 20-22). 3. The judgments of God came upon him for it. The Syrians invaded him (v. 23, 24). He was struck with sore diseases; his own servants conspired against him and slew him; and, as a mark of infamy upon him, he was not buried in the burying-place of the kings (v. 25-27). Verses 1-14 This account of Joash's good beginnings we had as it stands here 2 Ki. 12:1, etc., though the latter part of this chapter, concerning his apostasy, we had little of there. What is good in men we should take all occasions to speak of and often repeat it; what is evil we should make mention of but sparingly, and no more than is needful. We shall here only observe, 1. That it is a happy thing for young people, when they are setting out in the world, to be under the direction of those that are wise and good and faithful to them, as Joash was under the influence of Jehoiada, during whose time he did that which was right. Let those that are young reckon it a blessing to them, and not a burden and check upon them, to have those with them that will caution them against that which is evil and advise and quicken them to that which is good; and let them reckon it not a mark of weakness and subjection, but of wisdom and discretion, to hearken to such. He that will not be counselled cannot be helped. It is especially prudent for young people to take advice in their marriages, as Joash did, who left it to his guardian to choose him his wives, because Jezebel and Athaliah had been such plagues, v. 3. This is a turn of life which often proves either the making or marring of young people, and therefore should be attended to with great care. 2. Men may go far in the external performances of religion, and keep long to them, merely by the power of their education and the influence of their friends, who yet have no hearty affection for divine things nor any inward relish of them. Foreign inducements may push men on to that which is good who are not actuated by a living principle of grace in their hearts. 3. In the outward expressions of devotion it is possible that those who have only the form of godliness may out-strip those who have the power of it. Joash is more solicitous and more zealous about the repair of the temple than Jehoiada himself, whom he reproves for his remissness in that matter, v. 6. It is easier to build temples than to be temples to God. 4. The repairing of churches is a good work, which all in their places should promote, for the decency and conveniency of religious assemblies. The learned tell us that in the Christian church, anciently, part of the tithes were applied that way. 5. Many a good work would be done that now lies undone if there were but a few active men to stir in it and to put it forward. When Joash found the money did not come in as he expected in one way he tried another way, and that answered the intention. Many have honesty enough to follow that have not zeal enough to lead in that which is good. The throwing of money into a chest, through a hole in the lid of it, was a way that had not been used before, and perhaps the very novelty of the thing made it a successful expedient for the raising of money; a great deal was thrown in and with a great deal of cheerfulness: they all rejoiced, v. 10. An invention to please people's humour may sometimes bring them to their duty. Wisdom herein is profitable to direct. 6. Faithfulness is the greatest praise and will be the greatest comfort of those that are entrusted with public treasure or employed in public business. The king and Jehoiada faithfully paid the money to the workmen, who faithfully did the work, v. 12, 13. |
