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 trumpet of the three angels, which are yet to sound! An angel. 'Aleph (') A B, Vulgate, Syrian, Coptic, read, for "angel," 'an eagle:' symbol of judgment descending like the king of birds pouncing on the prey. Alluding to Matthew 24:28. Compare this fourth trumpet and the flying eagle with the fourth seal introduced by the fourth living creature: "like a flying eagle," Revelation 4:7; Revelation 6:7-8: the aspect of Jesus presented by the fourth evangelist. John is compared in the cherubim, by primitive interpretation, to a flying eagle: Christ's divine majesty is set forth in the Gospel, His judicial visitations in the Revelation, of John. Contrast "another angel" (messenger) with "the everlasting gospel," Revelation 14:6.
Through the midst of heaven - `in the mid-heaven,' at the meridian: where the eagle is conspicuous to all.
The inhabiters of the earth - the "men of the world," whose 'portion is in this life' (Psalms 17:14); upon whom the martyrs had prayed that their blood might be avenged (Revelation 6:10). Not for personal revenge, but zeal for the honour of God against the foes of God and His Church (Psalms 139:21-22).
The other - `the remaining voice.'
