Revelation 9:19

For the power of the horses is in their mouths and in their tails , for their tails are like serpents with heads , and by means of them they wound .

The power of the horses was in their mouths and in their tails; for their tails were like snakes, having heads with which they inflict injury.

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.
