The Second Trumpet in Isaiah 2:12-16,
the prophet is speaking of the Great Day
of the Lord. "The day of the Lord shall
be upon everyone that is high and lofty. .
. . .And upon all the ships of Tarshish. . ."

Besides the effects of this falling object
will be that the sea will turn to blood.
Whatever causes it, dead animals, or
other causes, we don't know.

Under the judgments upon Egypt, the
waters turned to blood, Exodus 7:20.
We can expect a literal fulfillment also
from this Second Trumpet.
