17 And it shall be in the last days, said God, I will pour out of My Spirit upon all flesh, and your sons and your daughters shall prophesy, and your young men shall see visions, and your old men shall dream dreams;
18 and also upon My men-servants, and upon My maid-servants, in those days, I will pour out of My Spirit, and they shall prophesy;
19 and I will give wonders in the heaven above, and signs upon the earth beneath -- blood, and fire, and vapour of smoke,
20 the sun shall be turned to darkness, and the moon to blood, before the coming of the day of the Lord -- the great and illustrious;
21 and it shall be, every one -- whoever shall call upon the name of the Lord, he shall be saved.
