and the Ever-living One [living in and beyond all time and space]. I died, but see, I am alive forevermore, and I have the keys of [absolute control and victory over] death and of Hades (the realm of the dead).

And no one in heaven or on earth or under the earth [in Hades, the realm of the dead] was able to open the scroll or look into it.

So I looked, and behold, an ashen (pale greenish gray) horse [like a corpse, representing death and pestilence]; and its rider’s name was Death; and Hades (the realm of the dead) was following with him. They were given authority and power over a fourth part of the earth, to kill with the sword and with famine and with plague (pestilence, disease) and by the wild beasts of the earth.
