Their. B C 'Aleph (') read, 'the power of the horses;' A х topon (G5117)], 'of the places.'
In their mouth - whence issued the fire, smoke, and brimstone (Revelation 9:17). Considering the parallelism of this sixth trumpet to the sixth seal, probably events are intended immediately preceding the Lord's coming.

Mohammed is a forerunner of him, not the exhaustive fulfiller of the prophecy. Satan will, toward the end, bring out all the powers of hell for the last conflict (note, "devils," Revelation 9:20: cf. Revelation 9:1-2; Revelation 9:17-18).
With them - the serpent heads with venomous fangs.
Hurt, х adikousin (G91)] - 'do wrong,' 'injury.'
