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 (Kg2 10:32), threatened Judah and Jerusalem likewise, took Gath, a strong city (Kg2 12:17), 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 (Kg2 12:18), 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, Ch2 24:23, Ch2 24:24.
II. His life became an easy prey to his own servants. They conspired against him and slew him (Kg2 12:20, Kg2 12:21), 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.

Took 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; Ch2 24:23.

For Jozachar the son of Shimeath,.... Said to be an Ammonitess, and this man's name Zabad, Ch2 24:26,

and Jehozabad the son of Shomer, his servants; who is said in the same place to be the son of Shimrith a Moabitess:

these smote him, and he died; justly did he fall by the hands of such persons for his idolatry:

and they buried him with his fathers in the city of David; but not in the sepulchres of the kings, because of his idolatry and murder of a priest of the Lord:

and Amaziah his son reigned in his stead; the conspirators not seeking the kingdom, but vengeance on him for his sins, which, whether right in them to do, was suffered by the Lord.

Then Hazael . . . fought against Gath--(See on Ch2 24:23).
