11 But Amaziah would not listen. So King Jehoash of Israel went up; he and King Amaziah of Judah faced one another in battle at Beth-shemesh, which belongs to Judah. 12 Judah was defeated by Israel; everyone fled home. 13 King Jehoash of Israel captured King Amaziah of Judah son of Jehoash, son of Ahaziah, at Beth-shemesh; he came to Jerusalem, and broke down the wall of Jerusalem from the Ephraim Gate to the Corner Gate, a distance of four hundred cubits. 14 He seized all the gold and silver, and all the vessels that were found in the house of the Lord and in the treasuries of the king's house, as well as hostages; then he returned to Samaria.

15 Now the rest of the acts that Jehoash did, his might, and how he fought with King Amaziah of Judah, are they not written in the Book of the Annals of the Kings of Israel? 16 Jehoash slept with his ancestors, and was buried in Samaria with the kings of Israel; then his son Jeroboam succeeded him. 17 King Amaziah son of Joash of Judah lived fifteen years after the death of King Jehoash son of Jehoahaz of Israel. 18 Now the rest of the deeds of Amaziah, are they not written in the Book of the Annals of the Kings of Judah? 19 They made a conspiracy against him in Jerusalem, and he fled to Lachish. But they sent after him to Lachish, and killed him there. 20 They brought him on horses; he was buried in Jerusalem with his ancestors in the city of David.

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.

Commentary on 2 Kings 14:15-22

(Read 2 Kings 14:15-22)

Amaziah survived his conqueror fifteen years. He was slain by his own subjects. Azariah, or Uzziah, seems to have been very young when his father was slain. Though the years of his reign are reckoned from that event, he was not fully made king till eleven years afterwards.
