Then Amaziah sent messengers to Jehoash, the son of Jehoahaz son of Jehu, king of Israel, saying, Come, {d} let us look one another in the face.

(d) Let us fight hand to hand, and try it by battle, and not destroy one another's cities.

Wesley's Notes

14:8 Sent - This challenge he sent, from self - confidence, and a desire of advancing his glory. But he that is fond either of fighting or going to law, will probably be the first that repents it.

Jamieson-Fausset-Brown Bible Commentary

2Ki 14:8-16. Joash Defeats Him.

8. Amaziah sent messengers to Jehoash, the son of Jehoahaz, son of Jehu, king of Israel-This bold and haughty challenge, which was most probably stimulated by a desire of satisfaction for the outrages perpetrated by the discharged auxiliaries of Israel (2Ch 25:13) on the towns that lay in their way home, as well as by revenge for the massacre of his ancestors by Jehu (2Ki 9:1-37) sprang, there is little doubt, from pride and self-confidence, inspired by his victory over the Edomites.

Matthew Henry's Concise Commentary

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.
