28 And it shall come to pass after this that I will pour out my Spirit upon all flesh; and your sons and your daughters shall prophesy, your old men shall dream dreams, your young men shall see visions: 29 and even upon the slaves and upon the handmaids in those days will I pour out my spirit.
30 And I will show wonders in the heaven and in the earth, blood, and fire, and pillars of smoke. 31 The sun shall be turned into darkness and the moon into blood before the great and the terrible day of the LORD comes. 32 And it shall come to pass that whoever shall call on the name of the LORD shall escape: for in Mount Zion and in Jerusalem shall be salvation, as the LORD has said, and in those who are left, to whom the LORD shall have called.
