Revelation 9:2

There arose a smoke out of the pit,— As a great smoke hinders the sight, so do errors the understanding. St. John keeps to the allegory, says Grotius: a smoke takes from us the sight of the stars. Smoke, especially when proceeding from a fierce fire, is also a representation of devastation. Thus when Abraham beheld the destruction of Sodom and Gomorrah, the smoke of the country went up, as the smoke of a furnace. The great displeasure of God is represented by the same figurative expressions of smoke and fire, Psalms 18:7 Psalms 18:7.
