Complete Commentary on the Whole Bible, by Matthew Henry, at sacred-texts.com
(Kg2 11:1-12) Athaliah usurps the government of Judah, Jehoash made king.
(Kg2 11:13-16) Athaliah put to death.
(Kg2 11:17-21) The worship of the Lord restored.
Athaliah destroyed all she knew to be akin to the crown. Jehoash, one of the king's sons, was hid. Now was the promise made to David bound up in one life only, and yet it did not fail. Thus to the Son of David, the Lord, according to his promise, will secure a spiritual seed, hidden sometimes, and unseen, but hidden in God's pavilion, and unhurt. Six years Athaliah tyrannized. Then the king was brought forward. A child indeed, but he had a good guardian, and, what was better, a good God to go to With such joy and satisfaction must the kingdom of Christ be welcomed into our hearts, when his throne is set up there, and Satan the usurper is cast out. Say, Let the King, even Jesus, live, for ever live and reign in my soul, and in all the world.
Athaliah hastened her own destruction. She herself was the greatest traitor, and yet was first and loudest in crying, Treason, treason! The most guilty are commonly the most forward to reproach others.
King and people would cleave most firmly to each other, when both had joined themselves to the Lord. It is well with a people, when all the changes that pass over them help to revive, strengthen, and advance the interests of religion among them. Covenants are of use, both to remind us of, and bind us to, the duties already binding on us. They immediately abolished idolatry; and, pursuant to the covenant with one another, they expressed mutual readiness to help each other. The people rejoiced, and Jerusalem was quiet. The way for people to be joyful and at peace, is to engage fully in the service of God; for the voice of joy and thanksgiving is in the dwellings of the righteous, but there is no peace for the wicked.
