Here God gives people the opportunity to
repent; an angel declares the next three
trumpets will be worse.

Revelation 8:13
"And I beheld, and heard an angel
flying through the midst of heaven,
saying with a loud voice,
Woe, woe, woe,
to the inhabiters of
the earth
by reason of the other
voices of the
trumpets of the three angels, which
are yet to sound."
