Foam
denotes "to foam at the mouth" (akin to aphros, "foam;" see B.), Mar 9:18, Mar 9:20.
"to foam out, or up" (epi, "up," and No. 1), is used metaphorically in Jud 1:13, of the impious libertines, who had crept in among the saints, and "foamed" out their own shame with swelling words. The metaphor is drawn from the refuse borne on the crest of waves and cast up on the beach. "foam," occurs in Luk 9:39, where it is used with the preposition meta, "with," lit., "(teareth him) with (accompanied by) foam."
