Let the nations rouse themselves, and come up to the valley of Jehoshaphat; for there will I sit to judge all the nations round about.
Joel 3:10 Beat your ploughshares into swords, and your pruning-knives into spears; let the weak say, I am strong.

Joel 3:13 Put in the sickle, for the harvest is ripe: come, get you down, for the press is full, the vats overflow; for their wickedness is great.
Joel 3:14 Multitudes, multitudes in the valley of decision! For the day of Jehovah is at hand in the valley of decision.
The verse centers on "nations", "rouse", "themselves", "come", "valley", "jehoshaphat", and "judge". It is saying that the verse draws attention to "nations" and "rouse", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 11's "Haste ye and come all ye nations..." into verse 13's "Put in the sickle for the harvest...", so "nations" and "rouse" belong inside that flow. In Joel context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "nations" and "rouse" with trust shaped by these words, not by a vague optimism outside the passage.
