17 And after the death of Jehoiada come in have heads of Judah, and bow themselves to the king; then hath the king hearkened unto them, 18 and they forsake the house of Jehovah, God of their fathers, and serve the shrines and the idols, and there is wrath upon Judah and Jerusalem for this their guilt. 19 And He sendeth among them prophets, to bring them back unto Jehovah, and they testify against them, and they have not given ear; 20 and the Spirit of God hath clothed Zechariah son of Jehoiada the priest, and he standeth over-against the people, and saith to them, 'Thus said God, Why are ye transgressing the commands of Jehovah, and prosper not? because ye have forsaken Jehovah—He doth forsake you.' 21 And they conspire against him, and stone him with stones by the command of the king, in the court of the house of Jehovah, 22 and Joash the king hath not remembered the kindness that Jehoiada his father did with him, and slayeth his son, and in his death he said, 'Jehovah doth see, and require.'

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.
