Exodus 10:21

The Ninth Blow: Darkness

10:21 The Lord said to Moses, “Extend your hand toward heaven so that there may be darkness over the land of Egypt, a darkness so thick it can be felt.”

Isaiah 60:2

60:2 For, look, darkness covers the earth

and deep darkness covers the nations,

but the Lord shines on you;

his splendor appears over you.
