And they conspired against him, and stoned him with stones at the {m} commandment of the king in the court of the house of the LORD.

(m) There is no rage so cruel and beastly as of them whose hearts God has hardened, and who delight more in superstition and idolatry than in the true service of God and pure simplicity of his word.

Wesley's Notes

24:21 Stoned him - They stoned him immediately, without even colour of law; as horrid a piece of wickedness, as any we read of in all the history of the kings. That ever such a villainy should be committed, by men, by Israelites, in contempt and violation of everything that is just, honourable, and sacred! The Jews say, there were seven transgressions in one: They killed a priest, a prophet, a judge; they shed innocent blood; polluted the court of the temple, the Sabbath, and the day of expiation: for on that day, their tradition says, this happened.

Matthew Henry's Concise Commentary

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.
