John Trapp on Hosea 10:7

Verſ. 7. As for Samaria, her king is cut off, as the feam upon the waters,] An apt ſimile (whereof this prophet is full) Her king, (not her idols, as ſome ſenſe it) though gotten into Samaria, a ſtrong city, ſo well victualled and fortified, as to hold out a ſiege of three years continuance, yet ſhall be cut off, or ſilenced as Chap. 4.7. as the foam upon the waters, bulla evanida, more weak then water, whereof it ariſeth, and whereby it is wherried away, and cannot reſiſt: or, as a bubble blown up by every ſmall wind, and as eaſily blown out again; it no ſooner appears but it diſappeares. Lo ſuch are the greateſt kings and kingdoms, when God taketh them in their wickedneſs. He cuts off the ſpirits of Princes, Pſal. 76.12. he ſlips them off, (ſo the Hebrew is) as one would ſlip off a flower between ones fingers; or as one would ſlip off a bunch of grapes. The kingdoms of the earth are like foam upon the waters. 1. For their ſeeming brightneſſe. 2. For their great eminence. 3. For their inſtability and inability to reſiſt. 4. For their ſudden fall, and diſappearance. The Turkiſh Empire (which hath ſwallowed up ſo many glorious Empires and renowned kingdoms) laboureth with nothing more then the weightineſſe of it ſelf: and ſhall ſhortly be cut off as foam, and live no otherwiſe then by fame, as others now do: though for the preſent, it be no whit inferiour, in greatneſſe, and ſtrength to the greateſt Monarchies that ever yet were upon the face of the earth; the Roman Empire onely excepted.
