Joel 2:29-31

International Children’s Bible

²⁹ At that time I will give my Spirit
    even to servants, both men and women.
³⁰ I will show miracles
    in the sky and on the earth:
    blood, fire and thick smoke.
³¹ The sun will become dark.
    The moon will become red as blood.
    And then the Lord’s overwhelming and terrible day of judging will come.
