Revelation 9:19
King James Version (1769 Blayney revision, with Apocrypha) · Berean Standard Bible
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 was in their mouths and in their tails; indeed, their tails were like snakes, having heads with which to inflict harm.
