"And it shall come to pass afterward, that I will pour out my spirit on all flesh; your sons and your daughters shall prophesy, your old men shall dream dreams, and your young men shall see visions.
Even upon the menservants and maidservants in those days, I will pour out my spirit.
"And I will give portents in the heavens and on the earth, blood and fire and columns of smoke.
The sun shall be turned to darkness, and the moon to blood, before the great and terrible day of the LORD comes.
And it shall come to pass that all who call upon the name of the LORD shall be delivered; for in Mount Zion and in Jerusalem there shall be those who escape, as the LORD has said, and among the survivors shall be those whom the LORD calls.
