Revelation 8:12 Third part of the sun was smitten

¹² And the fourth angel sounded, and the third part of the sun was smitten, and the third part of the moon, and the third part of the stars; so as the third part of them was darkened, and the day shone not for a third part of it, and the night likewise. -Revelation 8:12 King James Version (KJV)

523.

Verse 12. And the fourth angel sounded, and the third part of the sun was smitten, and the third part of the moon, and the third part of the stars; and the third part of them was darkened, that the day should not shine for the third part of it, and the night likewise. 12. "And the fourth angel sounded," signifies influx out of heaven, and the fourth consequent change (n. 524); "and the third part of the sun was smitten, and the third part of the moon, and the third part of the stars," signifies that all good of love, all good and truth of faith, and all knowledge of good and truth, perished (n. 525); "and the third part of them was darkened," signifies that all these were changed into falsities of evil and into evils of falsity (n. 526); "that the day should not shine for the third part of it, and the night likewise," signifies that the spiritual light of truth and the natural light of truth were completely extinguished (n. 527).
