ἵππος

When we put bits into the mouths of horses to make them obey us, we can guide the whole animal.

Then I saw heaven standing open, and there before me was a white horse. And its rider is called Faithful and True. With righteousness He judges and wages war.

Then I saw the beast and the kings of the earth with their armies assembled to wage war against the One seated on the horse, and against His army.

Then another horse went forth. It was bright red, and its rider was granted permission to take away peace from the earth and to make men slay one another. And he was given a great sword.

And the locusts looked like horses prepared for battle, with something like crowns of gold on their heads, and faces like the faces of men.
