| Barnes' Notes on the Bible Athaliah's destruction of the seed royal had left Joash without a natural successor, and his marriage at the earliest suitable age, was, therefore, a matter of state policy. One of his wives in question was probably "Jehoaddan of Jerusalem," the mother of Amaziah 2 Chronicles 25:1, who must have been taken to wife by Joash as early as his 21st year.
Gill's Exposition of the Entire BibleAnd Jehoiada took for him two wives,.... Not for himself; he had a wife who was aunt to King Joash, and he had sons who were concerned with him in anointing him, 2 Chronicles 22:11 and was now upwards of one hundred years of age; but for the king, when he was at an age fit for marriage, he advised him to marry, and proposed wives to him, whom he thought would be agreeable; for, observing what mischief was done both in church and state through Jehoram's marrying Athaliah, he was desirous of preventing any such disagreeable marriage; and as the young king was in all things guided and directed by him, so he was in this; and no doubt they were good women he pitched upon, and proposed to the king; one of them was Jehoadan, 2 Chronicles 25:1, but the name of the other we know not: and he begat sons and daughters; how many is not said, nor do we read of the names of any of them, but of Amaziah who succeeded him.

Jamieson-Fausset-Brown Bible Commentary3. Jehoiada took for him two wives-As Jehoiada was now too old to contract such new alliances, the generality of interpreters apply this statement to the young king.
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. |
