Both prophecies in Revelation and Joel
tells that God's people who earnestly seek
Him are protected.

The locust-demons or locust-horses can
not touch or harm those who have the
seal of God. "And it was commanded them
that they should not hurt. . .only those men
which have not the seal of God on their
foreheads" Revelation 9:4 This refers to
Israelites who were sealed. Revelation 7:
1-12

In Joel 2, Israel, is commanded "to weep
between the porch and the altar" and to
seek mercy from God. Joel 2:17

This evidence is strong that the locust-
horses of Revelation 9 that came from the
Pit during the Fifth Trumpet are the same
as those in the prophecy of Joel 2.
