The Second Bowl of God's wrath / plague (Rev 16:3):
1. Poured into the sea.
2. Causes the seas to became blood and killed all living creatures in it.
3. With the poisoning of all salt water, all seafood becomes unavailable. The Second Trumpet
had already poisoned 1/3 of all salt water (Rev 8:8-9).
In light of the eagle's woe for "those who dwell on the earth" (Rev 8:13;
11:14), the bowl plagues represent the third, last woe, and the only
remaining judgments against those left on earth; they represent the "reaping" by the angel (Rev 14:18-20).
The reaping figuratively speaks of gathering the "ripe" grapes and throwing them into the
great wine press of God's wrath "outside the city" (Rev 14:18-19), which
is a reference to the bowl judgments (Rev 16:1-21). This period of
reaping includes the angelic assistance of carrying out Jesus Christ's judgment at Armageddon, because it is
Jesus who treads upon the grapes in the great wine press of God's wrath (Rev 19:15-21).
