“And I beheld when he had opened the sixt seale, and loe, there was a great earthquake, and the Sunne became blacke as sackecloth of haire, and the Moone became as blood.”
1611 King James Version (KJV)
6:12 And I saw - This sixth seal seems particularly to point out God's judgment on the wicked departed. St. John saw how the end of the world was even then set before those unhappy spirits. This representation might be made to them, without anything of it being perceived upon earth. The like representation is made in heaven, #Rev 11:18|. And there was a great earthquake - Or shaking, not of the earth only, but the heavens. This is a farther description of the representation made to those unhappy souls.
Re 6:12 THE SIXTH SEAL. There was a great earthquake. The symbol of political or moral agitation and upheaval. The sun became black . . . and the moon became as blood. The "sun", "moon", and "stars" are symbols of earthly dignitaries, great lights in the political or religious heavens. In the dream of Joseph, which so maddened his brethren, these terms are used in this meaning, as well as by the ancient prophets. In the East it was common to liken the king or emperor to the sun, and the stars as the symbols of princes or rulers. For the use of the term we refer the reader to Da 8:10. The blackness of the sun and the bloody hue of the moon point out scenes of mourning and bloodshed among rulers and princes.
