12 And I beheld when he had opened the sixth seal, and, lo, there was a great earthquake; and the sun became black as sackcloth of hair, and the moon became as blood;
First, what is meant by “sackcloth of hair” (black?) and second, do you think this correlates with Joel 2:31:
31 The sun shall be turned into darkness, and the moon into blood, before the great and terrible day of the Lord come.
Third, how likely is it that these eclipses (?) are referring to March 20 and April 4, 2015?
