Joel 2:29-31

World English Bible

²⁹ And also on the servants and on the handmaids in those days,
    I will pour out my Spirit.
³⁰ I will show wonders in the heavens and in the earth:
    blood, fire, and pillars of smoke.
³¹ The sun will be turned into darkness,
    and the moon into blood,
    before the great and terrible day of Yahweh comes.
