Then afterward 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 on the male and female slaves, in those days, I will pour out my spirit.
I will show 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.
Then everyone who calls on the name of the Lord shall be saved; 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.
