'Falling' in the Bible

And the stars of heaven were falling to the earth, like green fruit from a tree before the force of a great wind.

The first blew his trumpet; and there came hail and fire, mixed with blood, falling upon the earth; and a third part of the earth was burnt up, and a third part of the trees and all the green grass.

And at the sounding of the fifth angel I saw a star falling from heaven to the earth: and there was given to him the key of the great deep.

These witnesses have authority to close the heavens in order to keep rain from falling while they are prophesying. They also have authority to turn bodies of water into blood and to strike the earth with any plague, as often as they desire.
