Zechariah 14:12
And the LORD will send a plague on all the nations that fought against Jerusalem. Their people will become like walking corpses, their flesh rotting away. Their eyes will rot in their sockets, and their tongues will rot in their mouths.
Zechariah 14:13
On that day they will be terrified, stricken by the LORD with great panic. They will fight their neighbors hand to hand.

There are several other biblical passages that allude to a plague that will decimate mankind in the end times.

Many people take the bible as the truth, and also see it as a book of prophecy. Could we have received warning of the impending rising of the undead from antiquity? We don’t have to go far to rationalize this. Prophets in ancient times may have seen exactly what happened, but didn’t understand the science behind it to describe it accurately. They may have seen the biological cause engineered in a lab and unleashed upon the world, but could only use simple words to describe it.

There are currently so many end times prophecies that it can make your head spin. Almost all of them don’t point to an exact cause of the apocalypse, but the bible seems to point to the undead several times

Revelation 11:6
These men have power to shut up the sky so that it will not rain during the time they are prophesying; and they have power to turn the waters into blood and to strike the earth with every kind of plague as often as they want.

Revelation 11:8
Their bodies will lie in the street of the great city, which is figuratively called Sodom and Egypt, where also their Lord was crucified.

Revelation 11:11
But after the three and a half days a breath of life from God entered them, and they stood on their feet, and terror struck those who saw them.

Ezekiel 37:10
So I prophesied as he commanded me, and breath entered them; they came to life and stood up on their feet–a vast army.

The bible is rife with resurrection, the dead coming to life, and stories and illiterations to the end of times. Perhaps, the plague God uses to wipe the earth clean is a plague of Zombies. You can also point to end times prophecy references of Locusts and say that zombies could also be considered as a locust, devouring all life. At this point, all we can do is speculate and prepare. We don’t know how or when the world will end, but we can be ready if it is survivable.

***Notes***
The end of the world can be described several ways:
1. A literal end, where the entire world is destroyed.
2. An end to the way the whole world sees itself.
3. A massive culling of the world’s population so that it is more in balance.
4. A massive culling of the world’s population so that it can be enslaved by those in power. (See Conspiracy)
