Acts 2:17-20

17"'And in the last days it shall be, God declares, that I will pour out my Spirit on all flesh, and your sons and your daughters shall prophesy, and your young men shall see visions, and your old men shall dream dreams;

18even on my male servants and female servants in those days I will pour out my Spirit, and they shall prophesy.

19And I will show wonders in the heavens above and signs on the earth below, blood, and fire, and vapor of smoke;

20the sun shall be turned to darkness and the moon to blood, before the day of the Lord comes, the great and magnificent day.
