That Joel 3 seems to mirror by common theme, the events of Rev 14 through 16, specifically, gathering to battle, harvests, grapes of wrath, earthquake, the 7th bowl, the return of the King:
9 Proclaim this among the nations:
“Prepare for war!
Wake up the mighty men,
Let all the men of war draw near,
Let them come up.
10 Beat your plowshares into swords
And your pruning hooks into spears;
Let the weak say, ‘I am strong.’”
11 Assemble and come, all you nations,
And gather together all around.
Cause Your mighty ones to go down there, O Lord.
12 “Let the nations be wakened, and come up to the Valley of Jehoshaphat;
For there I will sit to judge all the surrounding nations.
13 Put in the sickle, for the harvest is ripe.
Come, go down;
For the winepress is full,
The vats overflow—
For their wickedness is great.”
14 Multitudes, multitudes in the valley of decision!
For the day of the Lord is near in the valley of decision.
15 The sun and moon will grow dark,
And the stars will diminish their brightness.
16 The Lord also will roar from Zion,
And utter His voice from Jerusalem;
The heavens and earth will shake;
But the Lord will be a shelter for His people,
And the strength of the children of Israel. Joe 3:9-16
