River of Blood
Third bowl of wrath by the Third Angel.
Could this not happen as in Egypt? Exodus 7:19:24
Background Reading:
Revelation 16:4-7
The 3rd Bowl of Wrath - River of Blood
4 The third angel poured out his bowl on the rivers and springs of water, and they became blood.
5 Then I heard the angel in charge of the waters say:
"You are just in these judgments,
you who are and who were, the Holy One,
because you have so judged;
for they have shed the blood of your saints and prophets,
and you have given them blood to drink as they deserve."
7 And I heard the altar respond:
"Yes, Lord God Almighty,
true and just are your judgments"
