When will the trumpets in Revelation be blown?
The seven trumpets in Revelation are angelic trumpets, plural, blown by angels. They will sound at about the midpoint, according to the context. They are distinct from the singular trump of God, which is reserved for the calling out of the Body of Christ.
Les explains that Revelation 8:2 describes seven angels standing before God who were given seven trumpets, not the singular trump of God. He notes these are angelic trumpets, blown by angels, and they occur at about the midpoint. He contrasts this with 1 Corinthians 15, where the trump of God is singular and reserved for the calling out of the Body of Christ. He also mentions the Roman army's use of trumpets to issue commands.
