1 Joash was seven years old when he began to reign, and he reigned forty years in Jerusalem. His mother's name also was Zibiah of Beer-sheba. 2 And Joash did that which was right in the sight of the LORD all the days of Jehoiada the priest. 3 And Jehoiada took for him two wives; and he begat sons and daughters. 4 And it came to pass after this, that Joash was minded to repair the house of the LORD. 5 And he gathered together the priests and the Levites, and said to them, Go out unto the cities of Judah, and gather of all Israel money to repair the house of your God from year to year, and see that ye hasten the matter. Howbeit the Levites hastened it not. 6 And the king called for Jehoiada the chief, and said unto him, Why hast thou not required of the Levites to bring in out of Judah and out of Jerusalem the collection, according to the commandment of Moses the servant of the LORD, and of the congregation of Israel, for the tabernacle of witness? 7 For the sons of Athaliah, that wicked woman, had broken up the house of God; and also all the dedicated things of the house of the LORD did they bestow upon Baalim. 8 And at the king's commandment they made a chest, and set it without at the gate of the house of the LORD. 9 And they made a proclamation through Judah and Jerusalem, to bring in to the LORD the collection that Moses the servant of God laid upon Israel in the wilderness. 10 And all the princes and all the people rejoiced, and brought in, and cast into the chest, until they had made an end. 11 Now it came to pass, that at what time the chest was brought unto the king's office by the hand of the Levites, and when they saw that there was much money, the king's scribe and the high priest's officer came and emptied the chest, and took it, and carried it to his place again. Thus they did day by day, and gathered money in abundance. 12 And the king and Jehoiada gave it to such as did the work of the service of the house of the LORD, and hired masons and carpenters to repair the house of the LORD, and also such as wrought iron and brass to mend the house of the LORD. 13 So the workmen wrought, and the work was perfected by them, and they set the house of God in his state, and strengthened it. 14 And when they had finished it, they brought the rest of the money before the king and Jehoiada, whereof were made vessels for the house of the LORD, even vessels to minister, and to offer withal, and spoons, and vessels of gold and silver. And they offered burnt offerings in the house of the LORD continually all the days of Jehoiada. 15 But Jehoiada waxed old, and was full of days when he died; an hundred and thirty years old was he when he died. 16 And they buried him in the city of David among the kings, because he had done good in Israel, both toward God, and toward his house. 17 Now after the death of Jehoiada came the princes of Judah, and made obeisance to the king. Then the king hearkened unto them. 18 And they left the house of the LORD God of their fathers, and served groves and idols: and wrath came upon Judah and Jerusalem for this their trespass. 19 Yet he sent prophets to them, to bring them again unto the LORD; and they testified against them: but they would not give ear. 20 And the Spirit of God came upon Zechariah the son of Jehoiada the priest, which stood above the people, and said unto them, Thus saith God, Why transgress ye the commandments of the LORD, that ye cannot prosper? because ye have forsaken the LORD, he hath also forsaken you. 21 And they conspired against him, and stoned him with stones at the commandment of the king in the court of the house of the LORD. 22 Thus Joash the king remembered not the kindness which Jehoiada his father had done to him, but slew his son. And when he died, he said, The LORD look upon it, and require it. 23 And it came to pass at the end of the year, that the host of Syria came up against him: and they came to Judah and Jerusalem, and destroyed all the princes of the people from among the people, and sent all the spoil of them unto the king of Damascus. 24 For the army of the Syrians came with a small company of men, and the LORD delivered a very great host into their hand, because they had forsaken the LORD God of their fathers. So they executed judgment against Joash. 25 And when they were departed from him, (for they left him in great diseases,) his own servants conspired against him for the blood of the sons of Jehoiada the priest, and slew him on his bed, and he died: and they buried him in the city of David, but they buried him not in the sepulchres of the kings. 26 And these are they that conspired against him; Zabad the son of Shimeath an Ammonitess, and Jehozabad the son of Shimrith a Moabitess. 27 Now concerning his sons, and the greatness of the burdens laid upon him, and the repairing of the house of God, behold, they are written in the story of the book of the kings. And Amaziah his son reigned in his stead.
[AD 380] Apostolic Constitutions on 2 Chronicles 24:1
If in a small parish one advanced in years is not to be found, let some younger person who has a good report among his neighbors and is esteemed by them worthy of the office of a bishop—who has carried himself from his youth with meekness and regularity, like a much elder person—after examination and a general good report, be ordained in peace.… Joash governed the people at seven years of age. Wherefore, although the person is young, let him be meek, gentle and quiet.

[AD 258] Cyprian on 2 Chronicles 24:17-25
But if there are some who think that they can return to the Church not with prayers but with threats, or suppose that they can make a way for themselves, not with lamentation and atonements, but with terrors, let them take it for certain that against such the Church of the Lord stands closed; nor does the camp of Christ, unconquered and firm with the Lord's protection, yield to threats. The priest of God holding fast the Gospel and keeping Christ's precepts may be slain; he cannot be conquered. Zacharias, God's priest, suggests and furnishes to us examples of courage and faith, who, when he could not be terrified with threats and stoning, was slain in the temple of God, at the same time crying out and saying, what we also cry out and say against the heretics, "Thus saith the Lord, Ye have forsaken the ways of the Lord, and the Lord will forsake you."

[AD 435] John Cassian on 2 Chronicles 24:17-25
Some such thing we read of in the book of Chronicles. For Joash the king of Judah at the age of seven was summoned by Jehoiada the priest to the kingdom and by the witness of Scripture is commended for all his actions as long as the aforesaid priest lived. But hear what Scripture relates of him after Jehoiada’s death and how he was puffed up with pride and given over to a most disgraceful state. “But after the death of Jehoiada the princes went in and worshiped the king: and he was soothed by their services and hearkened to them. And they forsook the temple of the Lord, the God of their fathers, and served groves and idols, and great wrath came on Judah and Jerusalem because of this sin.” And after a little: “When a year was come about, the army of Syria came up against him: and they came to Judah and Jerusalem and killed all the princes of the people, and they sent all the spoils to the king to Damascus. And whereas there came a very small number of the Syrians, the Lord delivered into their hands an infinite multitude, because they had forsaken the Lord the God of their fathers; and on Joash they executed shameful judgments. And departing they left him in great diseases.” You see how the consequence of pride was that he was given over to shocking and filthy passions. For he who is puffed up with pride and has permitted himself to be worshiped as God, is (as the apostle says) “given over to shameful passions and a reprobate mind to do those things that are not convenient.” And because, as Scripture says, “everyone who exalts his heart is unclean before God,” he who is puffed up with swelling pride of heart is given over to most shameful confusion to be deluded by it, that when thus humbled he may know that he is unclean through impurity of the flesh and knowledge of impure desires, a thing that he had refused to recognize in the pride of his heart; and also that the shameful infection of the flesh may disclose the hidden impurity of the heart, which he contracted through the sin of pride, and that through the patent pollution of his body he may be proved to be impure, who did not formerly see that he had become unclean through the pride of his spirit.

[AD 735] Bede on 2 Chronicles 24:17-25
Zechariah was son of high priest Jehoiada, a man who was likewise very holy. They stoned Zechariah between the temple and the altar, as the Lord himself bore witness when he made mention of the blessed martyrs in the Gospel.
