Revelation 8:12

8:12 Then the fourth angel blew his trumpet, and a third of the sun was struck, and a third of the moon, and a third of the stars, so that a third of them were darkened. And there was no light for a third of the day and for a third of the night likewise.

Exodus 10:21-23

The Ninth Blow: Darkness

10:21 The Lord said to Moses, “Extend your hand toward heaven so that there may be darkness over the land of Egypt, a darkness so thick it can be felt.”

10:22 So Moses extended his hand toward heaven, and there was absolute darkness throughout the land of Egypt for three days. 10:23 No one could see another person, and no one could rise from his place for three days. But the Israelites had light in the places where they lived.

Joel 2:2

2:2 It will be a day of dreadful darkness,

a day of foreboding storm clouds,

like blackness spread over the mountains.

It is a huge and powerful army –

there has never been anything like it ever before,

and there will not be anything like it for many generations to come!

Joel 2:10

2:10 The earth quakes before them;

the sky reverberates.

The sun and the moon grow dark;

the stars refuse to shine.
