action, "they kept coming and saying" (elegon) in derision and
mock reverence with Ave (chaire, Hail!) as if to Caesar. Note
ho basileus (the king) in address. {They struck him with their
hands} (edidosan aut(9369) rapismata). Imperfect of did(936d)i,
repetition, "they kept on giving him slaps with their hands." See
