23 And it came to pass at the end of the year [that] the army of Syria came up against him; and they entered into Judah and Jerusalem, and destroyed all the princes of the people from among the people, and sent all the spoil of them to the king at Damascus. 24 Truly with a small company of men came the army of the Syrians, but Jehovah delivered a very great army into their hand, because they had forsaken Jehovah the God of their fathers; and they executed judgment upon Joash. 25 And when they had 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 did not bury him 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 And as to his sons, and the greatness of the burdens [laid] upon him, and the building of the house of God, behold, they are written in the treatise of the book of the kings. And Amaziah his son reigned in his stead.

Commentary on 2 Chronicles 24:15-27

(Read 2 Chronicles 24:15-27)

See what a great judgment on any prince or people, the death of godly, zealous, useful men is. See how necessary it is that we act in religion from inward principle. Then the loss of a parent, a minister, or a friend, will not be losing our religion. Often both princes and inferior people have been flattered to their ruin. True grace alone will enable a man to bring forth fruit unto the end. Zechariah, the son of Jehoiada, being filled with the Spirit of prophecy, stood up, and told the people of their sin. This is the work of ministers, by the word of God, as a lamp and a light, to discover the sin of men, and expound the providences of God. They stoned Zechariah to death in the court of the house of the Lord. Observe the dying martyr's words: The Lord look upon it, and require it! This came not from a spirit of revenge, but a spirit of prophecy. God smote Joash with great diseases, of body, or mind, or both, before the Syrians departed from him. If vengeance pursue men, the end of one trouble will be but the beginning of another. His own servants slew him. These judgments are called the burdens laid upon him, for the wrath of God is a heavy burden, too heavy for any man to bear. May God help us to take warning, to be upright in heart, and to persevere in his ways to the end.
