16. the trumpet--namely, of the besieging enemy
(Am 2:2).
alarm--the war shout [MAURER].
towers--literally, "angles"; for city walls used not to be built
in a direct line, but with sinuous curves and angles, so that besiegers
advancing might be assailed not only in front, but on both sides,
caught as it were in a cul-de-sac; towers were built especially at the
angles. So TACITUS describes the walls of
Jerusalem [Histories, 5.11.7].
