'Mouths' in the Bible

And thus I saw the horses in the vision, and them that sat on them, having breastplates of fire, and of jacinth, and brimstone: and the heads of the horses were as the heads of lions; and out of their mouths issued fire and smoke and brimstone.

By these three was the third part of men killed, by the fire, and by the smoke, and by the brimstone, which issued out of their mouths.

For the power of the horses is in their mouths and in their tails, for their tails, which resemble snakes, have heads, and they inflict injury with them.

If anyone wants to harm them, fire comes from their mouths and consumes their enemies; if anyone wants to harm them, he must be killed in this way.

No lie was found in their mouths; they are blameless.
