Santiago 3

Now if we put bits of iron into horses' mouths so that they may be guided by us, we have complete control of their bodies.

He aquí nosotros ponemos frenos en las bocas de los caballos para que nos obedezcan, y gobernamos todo su cuerpo.

Behold, we put bits in the horses’ mouths, that they may obey us; and we turn about their whole body.

Indeed, we put bits into the horses’ mouths so that they may obey us, and we guide their whole body.
