occurs as a translation of קֶצֶ (Ke'tseph, something broken): in Hosea 10:7, "As for Samaria, her king is cut off as the foam upon the water," after the Vulg. spuma. The Sept. doubtless gives the correct sense, φρύγανον, a dry twig or splinter. Horsley (Comment. in loc.) renders "bubble."
"Foam" is the true meaning of ἀφρός, froth (Luke 9:39; with its derivatives in Mark 9:18; Mark 9:20; Judges 1:13).
