Revelation 6:12-13

When He [the Lamb] broke open the sixth seal, I looked, and there was a great earthquake; and the sun grew black as sackcloth of hair, [the full disc of] the moon became like blood. [Joel 2:10, 31.] And the stars of the sky dropped to the earth like a fig tree shedding its unripe fruit out of season when shaken by a strong wind. [Isa. 34:4.]
