Hosea 10:7 - Albert Barnes' Notes on the Bible

Her king is cut off like foam - (Or, more probably, “a straw) on the” (literally, “face of the) water.” A bubble, or one of those little shreds which float in countless numbers on the surface of the water, give the same image of lightness, emptiness, worthlessness, a thing too light to sink, but driven impetuously, and unresistingly, here and there, at the impulse of the torrent which hurries it along. Such was the king, whom Israel had set in the highest place, in whom it had trusted, instead of God. So easily was Hoshea, their last king, swept away by the flood, which broke in on Ephraim, from Assyria. Piety is the only solidity; apart from piety all is emptiness.
