Joel 2:29-31

New International Reader's Version

²⁹ In those days I will pour out my Spirit
    on those who serve me, men and women alike.
³⁰ I will show wonders in the heavens and on the earth.
    There will be blood and fire and clouds of smoke.
³¹ The sun will become dark.
    The moon will turn red like blood.
    It will happen before the great and terrible day of the Lord comes.
