Acts 2:18-20

Revised Standard Version Catholic Edition

¹⁸ yea, and on my menservants and my maidservants in those days
I will pour out my Spirit; and they shall prophesy.
¹⁹ And I will show wonders in the heaven above
and signs on the earth beneath,
blood, and fire, and vapor of smoke;
²⁰ the sun shall be turned into darkness
and the moon into blood,
before the day of the Lord comes,
the great and manifest day.
