Joel 2:30–32

30 I will show wonders in the heavens

and on the earth,

blood and fire and billows of smoke.

31 The sun will be turned to darkness

and the moon to blood

before the coming of the great and dreadful day of the Lord.

32 And everyone who calls

on the name of the Lord will be saved;

for on Mount Zion and in Jerusalem

there will be deliverance,

as the Lord has said,

among the survivors

whom the Lord calls.
