Revelation 9:19 Meaning and Commentary

Revelation 9:19

For their power is in their mouth
In what proceeded out of their mouth, or seethed to do so; in their guns, and what came out of them:

and in their tails;
which may design their foot soldiers, which were as the tail to their horse, and who sometimes did great service; or their way of fighting when they fled, by casting up arrows into the air, which would fall upon the heads and horses of those that pursued them; or their ambushments, by which they destroyed many; or their perfidious violation of treaties; or it may be their tails may intend the doctrine of Mahomet, the false prophet, who is the tail, ( Isaiah 9:15 ) ,

for their tails [were] like unto serpents;
crooked, crafty, poisonous, and, pernicious:

and had heads;
every tail had a head to it; which may be understood of the officers of the foot soldiers, or of the priests and teachers of the Mahometan religion:

and with them they do hurt;
with their guns, the power in their mouth, they did hurt to the bodies of men; and with their false doctrines, their tails, they did hurt to the souls of men; the Ethiopic version here adds, "five months"; which seems to be taken from ( Revelation 9:10 ) .

Revelation 9:19 In-Context

17 And thus I saw the horses in the vision, and those sitting upon them, having breastplates of fire, and jacinth, and brimstone; and the heads of the horses [are] as heads of lions, and out of their mouths proceedeth fire, and smoke, and brimstone;
18 by these three were the third of men killed, from the fire, and from the smoke, and from the brimstone, that is proceeding out of their mouth,
19 for their authorities are in their mouth, and in their tails, for their tails [are] like serpents, having heads, and with them they do injure;
20 and the rest of men, who were not killed in these plagues, neither did reform from the works of their hands, that they may not bow before the demons, and idols, those of gold, and those of silver, and those of brass, and those of stone, and those of wood, that are neither able to see, nor to hear, nor to walk,
21 yea they did not reform from their murders, nor from their sorceries, nor from their whoredoms, nor from their thefts.
