'Pestilence' in the Bible

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.

For this reason in a single day her plagues (afflictions, calamities) will come, pestilence and mourning and famine, and she will be burned up with fire and completely consumed; for strong and powerful is the Lord God who judges her.
