8:13 And I looked, and I heard an eagle flying in midheaven, saying with a loud voice, "Woe, woe, woe, to those who dwell on the earth; because of the remaining blasts of the trumpet of the three angels who are about to sound!"

And I looked, and I heard an EAGLE (angel, King James Version) flying in midheaven, saying with a loud voice,

The oldest manuscripts all translate to EAGLE. This may be one and the same as the fourth living creature in Revelation 4:6-7. This is a special message to earth that John both saw and heard.

In "midheaven" tends to indicate this eagle (angel) physically flies over the earth visible to all below.

"WOE, WOE, WOE, to those who dwell on the earth, because of the remaining blasts of the trumpet of the THREE ANGELS who are about to sound!"

It is not so unusual to have angels (eagle) make announcements to earth. The birth of Christ was announced to shepherds in Luke 2:8-11. In Luke, that was a joyful announcement; in the next chapter, the WOE, WOE, WOE here indicates evil, psychological mind games, and mental anguish will be played out. In this chapter, the TRUMPETS mainly did physical damage to the earth.

The prophesy of Deuteronomy 28:49-57 may finally be fulfilled in these three WOES. It is described as "an eagle swoops down" meaning it will be carried out silently yet powerfully.
