Straight after those days of suffering, “The sun will become dark, and the moon will no longer shine. The stars will fall, and the powers in the sky will be shaken.”
When the fourth angel blew his trumpet, a third of the sun, a third of the moon, and a third of the stars were struck. They each lost a third of their light. So during a third of the day there was no light, and a third of the night was also without light.
