Matthew Henry · Verses 8–14
For some time after the division of the kingdoms, Judah suffered much from the enmity of Israel. After Asa's time, it suffered more by the friendship of Israel, and by the alliance made with them. Now we meet with hostility between them again. How may a humble man smile to hear two proud and scornful men set their wits on work, to vilify and undervalue one another! Unholy success excites pride; pride excites contentions. The effects of pride in others, are insufferable to those who are proud themselves. These are the sources of trouble and sin in private life; but when they arise between princes, they become the misery of their whole kingdoms. Jehoash shows Amaziah the folly of his challenge; Thine heart has lifted thee up. The root of all sin is in the heart, thence it flows. It is not Providence, the event, the occasion, whatever it is, that makes men proud, secure, discontented, or the like, but their own hearts do it. (2Ki 14:15-22)
