| Barnes' Notes on the Bible Jehoash did not submit without a struggle. See the details in Chronicles. It was not until his army was defeated that he followed the example of his ancestor, Asa, and bought the friendship of the Syrians with the temple treasures (1 Kings 15:18. Compare the conduct of Hezekiah, 2 Kings 18:15-16). Jehoram and Ahaziah - Though these two monarchs had been worshippers of Baal, yet they had combined with that idolatrous cult a certain amount of decent respect for the old religion. It is evident from this passage that they had made costly offerings to the temple.
Clarke's Commentary on the BibleTook all the hallowed things - He dearly bought a peace which was of short duration, for the next year Hazael returned, and Jehoash, having no more treasures, was obliged to hazard a battle, which he lost, with the principal part of his nobility, so that Judah was totally ruined, and Jehoash shortly after slain in his bed by his own servants; 2 Chronicles 24:23.
Gill's Exposition of the Entire BibleAnd Jehoash king of Judah took all the hallowed things that Jehoshaphat, and Jehoram, and Ahaziah, his fathers, kings of Judah, had dedicated,.... To sacred uses, and had laid up in the temple: and his own hallowed things: which he had devoted to the same uses: and all the gold that was found in the treasures of the house of the Lord: which were gifts and presents from divers persons for sacred services: and sent it to Hazael king of Syria, and he went away from Jerusalem; to bribe him, that he might desist from his purpose; which showed a meanness of spirit, and was the effect of his idolatry and apostasy, having forsaken the Lord, and being forsaken by him; in whom should have been his trust and confidence, and then he need not have been afraid to meet the king of Syria.
Geneva Study BibleAnd Jehoash king of Judah took all the hallowed things that Jehoshaphat, and Jehoram, and Ahaziah, his fathers, kings of Judah, had dedicated, and his own hallowed things, and all the gold that was found in the treasures of the house of the LORD, and in the king's house, and {i} sent it to Hazael king of Syria: and he went away from Jerusalem. (i) After the death of Jehoiada, Joash fell to idolatry: therefore God rejected him, and stirred up his enemy against him, whom he pacified with the treasures of the temple: for God would not be served with those gifts, seeing the king's heart was wicked.

Matthew Henry's Concise Commentary12:17-21 Let us review the character of Jehoash, and consider what we may learn from it. When we see what a sad conclusion there was to so promising a beginning, it ought to make us seek into our spiritual declinings. If we know any thing of Christ as the foundation of our faith and hope, let us desire to know nothing but Christ. May the work of the blessed Spirit on our souls be manifest; may we see, feel, and be earnest, in seeking after Jesus in all his fulness, suitableness, and grace, that our souls may be brought over from dead works to serve the living and true God.
Matthew Henry's Whole Bible CommentaryVerses 17-21 When Joash had revolted from God and become both an idolater and a persecutor the hand of the Lord went out against him, and his last state was worse than his first. I. His wealth and honour became an easy prey to his neighbours. Hazael, when he had chastised Israel (ch. 10:32), threatened Judah and Jerusalem likewise, took Gath, a strong city (v. 17), and thence intended to march with his forces against Jerusalem, the royal city, the holy city, but whose defence, on account of its sinfulness, had departed. Joash had neither spirit nor strength to make head against him, but gave him all the hallowed things, and all the gold that was found both in his exchequer and in the treasures of the temple (v. 18), to bribe him to march another way. If it were lawful to do this for the public safety, better part with the gold of the temple than expose the temple itself; yet, 1. If he had not forsaken God, and forfeited his protection, his affairs would not have been brought to this extremity, but he might have forced Hazael to retire. 2. He diminished himself, and made himself very mean, lost the honour of a prince and a soldier, and of an Israelite too, in alienating the dedicated things. 3. He impoverished himself and his kingdom. And, 4. He tempted Hazael to come again, when he could carry home so rich a booty without striking a stroke. And it had this effect, for the next year the host of Syria came up against Jerusalem, destroyed the prince, and plundered the city, 2 Chr. 24:23, 24. II. His life became an easy prey to his own servants. They conspired against him and slew him (v. 20, 21), not aiming at his kingdom, for they opposed not his son's succeeding him, but to be avenged on him for some crime he had committed; and we are told in Chronicles that his murdering the prophet, Jehoiada's son, was the provocation. In this, how unrighteous soever they were (vengeance was not theirs, nor did it belong to them to repay), God was righteous; and this was not the only time that he let even kings know that it was at their peril if they touched his anointed and did his prophets any harm, and that, when he comes to make inquisition for blood, the blood of prophets will run the account very high. Thus fell Joash, who began in the spirit and ended in the flesh. God usually sets marks of his displeasure upon apostates, even in this life; for they, of all sinners, do most reproach the Lord. |
