Passage
For behold in those days, and in that time when I shall bring back the captivity of Juda, and Jerusalem:
For behold in those days, and in that time when I shall bring back the captivity of Juda, and Jerusalem:
Joel 3:1 For behold in those days, and in that time when I shall bring back the captivity of Juda, and Jerusalem:
Joel 3:2 I will gather together all nations and will bring them down into the valley of Josaphat: and I will plead with them there for my people, and for my inheritance, Israel, whom they have scattered among the nations, and have parted my land.
Joel 3:3 And they have cast lots upon my people: and the boy they have put in the stews, and the girl they have sold for wine, that they might drink.
The verse centers on "behold", "days", "time", "shall", "bring", "back", "captivity", and "juda". It is saying that the verse draws attention to "behold" and "days", so its meaning should be read from those terms before moving to application.
The next verse adds "I will gather together all nations and...", so "behold" and "days" should be read forward into that movement. In Joel context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "behold" and "days" with trust shaped by these words, not by a vague optimism outside the passage.
