Revelation 8:9

“And the third part of the creatures which were in the sea, etc.] The fishes; by whom men are meant, the inhabitants of the Roman empire; (see <262904> Ezekiel 29:4,5), where by fish the Targum understands mighty princes and governors: and had life, died; were put to death by these savage and barbarous people, who killed all they met with, men, women, and children, young and old, rich and poor, high and low: and the third part of the ships were destroyed; by which may be designed either the cities and towns within such a part of the Roman jurisdiction, which were burnt or plundered by them; or their goods and effects, which they pillaged, and carried off the wealth and riches of the people,…”

“The symbolical interpreters take the ships here to be churches. For the Greek here for ships is not the common one, but that used in the Gospels of the apostolic vessel in which Christ taught: and the first churches were in the shape of an inverted ship: and the Greek for destroyed is also used of heretical corruptings (Ti1 6:5).”

“And the third part of the creatures which were in the sea, and had life, died - The effect was as if one-third of all the fish in the sea were cut off. Of course this is not to be taken literally. It is designed to describe an effect, pertaining to the maritime portion of the world, as if a third portion of all that was in the sea should perish. The natural interpretation would be to apply it to some invasion or calamity pertaining to the sea - to the islands, to the maritime regions, or to commerce. If the whole description pertains to the Roman empire, then this might be supposed to have particular reference to something that would have a bearing on the maritime parts of that empire. And…”

“And the third part of the creatures that were in the sea - That is, of all sorts of men, of every station and degree. Died - By those merciless invaders. And the third part of the ships were destroyed - It is a frequent thing to resemble a state or republic to a ship, wherein many people are embarked together, and share in the same dangers. And how many states were utterly destroyed by those inhuman conquerors! Much likewise of this was literally fulfilled. How often was the sea tinged with blood! How many of those who dwelt mostly upon it were killed! And what number of ships destroyed! Revelation 8:10”
