Meaning
"a herald" (akin to A, No. 2 and B, above), is used (a) of the "preacher" of the Gospel, 1Ti 2:7, 2Ti 1:11; (b) of Noah, as a "preacher" of righteousness, 2Pe 2:5.
Notes: (1) For "a preacher," in Rom 10:14, where the verb kerusso is used, see PREACH, A, No. 2. (2) Kerux indicates the "preacher" as giving a proclamation; euangelistes points to his message as glad tidings; apostolos suggests his relationship to Him by whom he is sent.
