2 Kings 14:9

By the thistle, a low and contemptible, yet troublesome shrub, he understands Amaziah; and by the cedar, himself, whom he intimates to be far stronger than he, and out of his reach, Give thy daughter to my son to wife; let us make a match, i.e. let us fight; only he expresseth this bloody work in a civil manner, as Amaziah had done, 2 Kings 14:8, and as Abner did, 2 Samuel 2:14. Or, let thy kingdom and mine be united under one king, as formerly they were; and let us decide it by a pitched battle, whether thou or I shall be that king. Or, as some expound it, by affirming that it was great arrogancy and presumption for him to desire a friendly league or affinity with him, he leaves him to guess how intolerable it was that he should undertake to wage war against him. Trod down the thistle; and with no less ease shall my soldiers tread down thee and thy forces.
