Isaiah 50:3

Treasury of Scripture Knowledge

I clothe the heavens with blackness, and I make sackcloth their covering.

Jehovah then said to Moses: Raise your hand toward the sky. Darkness thick enough to be felt will cover the land of Egypt.

He made the darkness his hiding place, his pavilion round about, the dark rain clouds his covering.

Now from the sixth hour there was darkness over all the land until the ninth hour.

When he opened the sixth seal I saw a great earthquake. The sun became black as sackcloth of hair and the moon became like blood.
