Joel 2:27-32

Then you will know that I am among my people Israel,
that I am the Lord your God, and there is no other.
Never again will my people be disgraced.

“Then, after doing all those things,
I will pour out my Spirit upon all people.
Your sons and daughters will prophesy.
Your old men will dream dreams,
and your young men will see visions.
In those days I will pour out my Spirit
even on servants—men and women alike.
And I will cause wonders in the heavens and on the earth—
blood and fire and columns of smoke.
The sun will become dark,
and the moon will turn blood red
before that great and terrible day of the Lord arrives.
But everyone who calls on the name of the Lord
will be saved,
for some on Mount Zion in Jerusalem will escape,
just as the Lord has said.
These will be among the survivors
whom the Lord has called.
