Revelation 6:12

(9) And I beheld when he had opened the sixth seal, and, lo, there was a great earthquake; and the sun became black as (c) sackcloth of hair, and the moon became as blood;

(9) The sixth sign, a narration, has two parts: the sign and the event. The sign is that the earth, heaven, and the things that are in them, for the horror of the sins of the world after those most heavy warnings from God, and complaints of the saints shall be shaken most severely, trembling in horrible manner, and losing their light, in this verse: things falling from heaven (Revelation 6:13) withdrawing themselves and fleeing from the greatness of the trouble (Revelation 6:14). So completely do all creatures depend on the will of God, and content themselves in his glory.

(c) So they called in old time those woven works that were of hair.
