For their power is in their mouth, and in their tails: for their tails were like unto serpents, and had heads, and with them they do hurt.

For the power of the horses is in their mouths, and in their tails. For, their tails are like to serpents, and have heads: and with them they hurt.

For the power of the horses is in their mouth and in their tails: for their tails are like serpents, having heads, and with them they injure.

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;

For the power of the horses is in their mouths and in their tails; their tails being like serpents, and having heads, and it is with them that they inflict injury.

For the power of the horses is in their mouths and in their tails: because their tails are like snakes, and have heads, and with them they give wounds.

For the power of these horses is in their mouths and in their tails. For their tails resemble serpents, having heads; and it is with these that they cause harm.

for the power of the horses lies in their mouths and in their tails. For their tails are like snakes, with heads, and it is with them that they do harm.

For their power is in their mouth - That is, as described in the fire, smoke, and brimstone that proceeded out of their mouths. What struck the seer as remarkable on looking on the symbol was, that this immense destruction seemed to proceed out of their mouths. It was not that they trampled down their enemies; nor that they destroyed them with the sword, the bow, or the spear: it was some new and remarkable power in warfare - in which the destruction seemed to proceed from fire, and smoke, and sulphur issuing from the mouths of the horses themselves.
And in their tails - The tails of the horses. This, of course, was something unusual and remarkable in horses, for naturally they have no power there. The power of a fish, or a scorpion, or a wasp, may be said to be in their tails, for their strength or their means of defense or of injury are there; but we never think of speaking in this way of horses. It is not necessary, in the interpretation of this, to suppose that the reference is literally to the tails of the horses, anymore than it is to suppose that the smoke, and fire, and brimstone literally proceeded from their mouths. John describes things as they appeared to him in looking at them from a considerable distance. From their mouths the horses belched forth fire, and smoke, and sulphur, and even their tails seemed to be armed for the work of death.
For their tails were like unto serpents - Not like the tails of serpents, but like serpents themselves.
And had heads - That is, there was something remarkable in the position and appearance of their heads. All serpents, of course, have heads; but John saw something unusual in this - or something so unique in their heads as to attract special attention. It would seem most probable that the heads of these serpents appeared to extend in every direction - as if the hairs of the horses' tails had been converted into snakes, presenting a most fearful and destructive image. Perhaps it may illustrate this to suppose that there is reference to the Amphisbaena, or two-headed snake. It is said of this reptile that its tail resembles a head, and that with this it throws out its poison (Lucan, vol. ix. p. 179; Pliny's Hist. Nat. vol. viii. p. 35). It really has but one head, but its tail has the appearance of a head, and it has the power of moving in either direction to a limited degree. If we suppose these snakes fastened to the tail of a horse, the appearance of heads would be very prominent and remarkable. The image is that of the power of destruction. They seemed like ugly and poisonous serpents instead of tails.
And with them they do hurt - Not the main injury, but they have the power of inflicting some injury by them.

Their power is in their mouth - From these the destructive balls are projected; and in their tails, the breech where the charge of gunpowder is lodged.
Their tails were like unto serpents, and had heads - If cannons are intended, the description, though allegorical, is plain enough; for brass ordnance especially are frequently thus ornamented, both at their muzzles and at their breech.

For their power is in their mouth, and in their tails: (14) for their tails [were] like unto serpents, and had heads, and with them they do hurt.
(14) That is, they are harmful on all sides: on whatever part you put your hand to them, or they touch you, they do hurt. So the former are called Scorpions, (Revelation 9:3).

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.

their--A, B, C and Aleph read, "the power of the horses."
in their mouth--whence issued the fire, smoke, and brimstone (Revelation 9:17). Many interpreters understand the horsemen to refer to the myriads of Turkish cavalry arrayed in scarlet, blue, and yellow (fire, hyacinth, and brimstone), the lion-headed horses denoting their invincible courage, and the fire and brimstone out of their mouths, the gunpowder and artillery introduced into Europe about this time, and employed by the Turks; the tails, like serpents, having a venomous sting, the false religion of Mohammed supplanting Christianity, or, as ELLIOTT thinks, the Turkish pachas' horse tails, worn as a symbol of authority. (!) All this is very doubtful. Considering the parallelism of this sixth trumpet to the sixth seal, the likelihood is that events are intended immediately preceding the Lord's coming. "The false prophet" (as Isaiah 9:15 proves), or second beast, having the horns of a lamb, but speaking as the dragon, who supports by lying miracles the final Antichrist, seems to me to be intended. Mohammed, doubtless, is a forerunner of him, but not the exhaustive fulfiller of the prophecy here: Satan will, probably, towards the end, bring out all the powers of hell for the last conflict (see on Revelation 9:20, on "devils"; compare Revelation 9:1-2, Revelation 9:17-18).
with them--with the serpent heads and their venomous fangs.
