Joel 

Chapter 1

Call a solemn assembly and gather to the house of the Lord, for the day of the Lord is at hand.

Chapter 2

War and desolation will precede the Second Coming—The sun and the moon will be darkened—The Lord will pour out His Spirit upon all flesh—There will be dreams and visions.

Chapter 3

All nations will be at war—Multitudes will stand in the valley of decision as the Second Coming draws near—The Lord will dwell in Zion.
