8 Then Amaziah sent representatives to Jehoash, the son of Jehoahaz, son of Jehu, king of Israel, saying, Come, let us have a meeting face to face. 9 And Jehoash, king of Israel, sent to Amaziah, king of Judah, saying, The thorn-tree in Lebanon sent to the cedar in Lebanon, saying, Give your daughter to my son for a wife: and a beast from the woodland in Lebanon went by, crushing the thorn under his feet. 10 It is true that you have overcome Edom and your heart is uplifted; let that glory be enough for you, and keep in your country; why do you make causes of trouble, putting yourself, and Judah with you, in danger of downfall? 11 But Amaziah gave no attention. So Jehoash, king of Israel, went up, and he and Amaziah, king of Judah, came face to face at Beth-shemesh, which is in Judah. 12 And Judah was overcome before Israel, so that they went in flight, every man to his tent. 13 And Jehoash, king of Israel, made Amaziah, king of Judah, the son of Jehoash, son of Ahaziah, prisoner at Beth-shemesh, and came to Jerusalem, and had the wall of Jerusalem pulled down from the doorway of Ephraim to the door in the angle, four hundred cubits. 14 And he took all the gold and silver and all the vessels which were in the house of the Lord and in the store-house of the king, together with those whose lives would be the price of broken faith, and went back to Samaria.

Commentary on 2 Kings 14:8-14

(Read 2 Kings 14:8-14)

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.
