The Fourth trumpet
Revelation 8:12 The fourth angel sounded his trumpet, and a third of the sun was struck, a third of the moon, and a third of the stars, so that a third of them turned dark. A third of the day was without light, and also a third of the night.
13 As I watched, I heard an eagle that was flying in midair call out in a loud voice: "Woe! Woe! Woe to the inhabitants of the earth, because of the trumpet blasts about to be sounded by the other three angels!"
The sun will be turned to darkness and the moon to blood before the coming of the great and glorious day of the Lord.
The sun and moon will be darkened, and the stars no longer shine.
The stars of heaven and their constellations will not show their light. The rising sun will be darkened and the moon will not give its light.
When I snuff you out, I will cover the heavens and darken their stars; I will cover the sun with a cloud, and the moon will not give its light.
