2 Kings 14:8

Let us look one another in the face Let us try our valour and strength in battle. Being flushed with his late great victory over the Edomites, and incensed by the injury which the dismissed, disgusted Israelites had lately done to his country in their return, (2 Chronicles 25:13,) he sent this challenge to the king of Israel. Perhaps he had the vanity to think he could subdue his kingdom, and reunite it to Judah. Had he challenged him merely to a personal duel, the error had remained with himself: but each of them must bring all his forces into the field, and thousands of lives must be sacrificed on both sides to his capricious humour! Hereby he showed himself proud, presumptuous, and prodigal of blood. They that challenge are chargeable with that beginning of strife which is as the letting out of water. And they that are fond either of fighting or going to law, may perhaps have enough of it quickly, and will probably be the first that repent it.
