2. Könige 14:8

For several successions after the division of the kingdoms that of Judah suffered much by the enmity of Israel. After Asa's time, for several successions, it suffered more by the friendship of Israel, and by the alliance and affinity made with them. But now we meet with hostility between them again, which had not been for some ages before. I. Amaziah, upon no provocation, and without showing any cause of quarrel, challenged Joash into the field (Kg2 14:8): "Come, let us look one another in the face; let us try our strength in battle." Had he challenged him to a personal duel only, the error would have remained with himself, but each must bring all their forces into the field, and thousands of lives on both sides must be sacrificed to his capricious humour.

Joash sent him a grave rebuke for his challenge, with advice to withdraw it, Kg2 14:9, Kg2 14:10. 1. He mortifies his pride, by comparing himself to a cedar, a stately tree, and Amaziah to a thistle, a sorry weed, telling him he was so far from fearing him that he despised him, and scorned as much to have any thing to do with him, or make any alliance with him, as the cedar would to match his daug…

14:8 Amaziah’s challenge to Israel’s King Jehoash may have been provoked by thoughts of revenge (see 2 Chr 25:13). Perhaps Amaziah had also become overly confident and proud because of his recent victory over Edom.
