The woes: “ One woe is past, behold there come two woes more hereafter” --9:12.
In 8:13 the flying angel announced three woes to enhance solemnity. Now, it was John speaking, not the angel, not the eagle, not one of the elders, nor one of the creatures, but John. As if to mark by count the three woes announced by the angel in Revelation 8:13, in recording tones John said: “ One woe is past: and, behold there come two woes more hereafter.”
A retrospective comment is in order here on the meaning of the expression “ third part” in the beginning of fifth trumpet--verses 7, 8, 10, 12--finds explanation in the three woes, each announcement of the angel representing a third part of the whole realm of the woes.
