Joel 2:28-32 And it shall come to pass afterward, [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:
2:29 And also upon the servants and upon the handmaids in those days will I pour out My Spirit.
2:30 And I will show wonders in the heavens and in the earth, blood, and fire, and pillars of smoke.
2:31 The "sun" shall be turned into darkness, and the "moon" into blood, before the great and the terrible day of the "I AM" come.
2:32 And it shall come to pass, [that] whosoever shall call on the name of the "I AM" shall be delivered: for in mount Zion and in Jerusalem shall be deliverance, as the "I AM" hath said, and in the remnant whom the "I AM" shall call. King of kings'Bible
