Proverbs 26:4

And, behold, all the men of Israel came to the king, and said unto the king, Why have our brethren the men of Judah stolen thee away, and have brought the king, and his household, and all David's men with him, over Jordan? And all the men of Judah answered the men of Israel, Because the king is near of kin to us: wherefore then be ye angry for this matter? have we eaten at all of the king's cost? or hath he given us any gift? And the men of Israel answered the men of Judah, and said, We have ten parts in the king, and we have also more right in David than ye: why then did ye despise us, that our advice should not be first had in bringing back our king? And the words of the men of Judah were fiercer than the words of the men of Israel.

And spake to them after the counsel of the young men, saying, My father made your yoke heavy, and I will add to your yoke: my father also chastised you with whips, but I will chastise you with scorpions.

Then Amaziah sent messengers to Jehoash, the son of Jehoahaz son of Jehu, king of Israel, saying, Come, let us look one another in the face. And Jehoash the king of Israel sent to Amaziah king of Judah, saying, The thistle that was in Lebanon sent to the cedar that was in Lebanon, saying, Give thy daughter to my son to wife: and there passed by a wild beast that was in Lebanon, and trode down the thistle. Thou hast indeed smitten Edom, and thine heart hath lifted thee up: glory of this, and tarry at home: for why shouldest thou meddle to thy hurt, that thou shouldest fall, even thou, and Judah with thee?

The beginning of strife is as when one letteth out water: therefore leave off contention, before it be meddled with.
