2 I will gather all nations and bring them down to the Valley of Jehoshaphat.[1]There I will put them on trial for what they did to my inheritance, my people Israel, because they scattered my people among the nations and divided up my land.

Matthew Henry's Commentary on Joel 3:2

Commentary on Joel 3:1-8

(Read Joel 3:1-8)

The restoration of the Jews, and the final victory of true religion over all opposers, appear to be here foretold. The contempt and scorn with which the Jews have often been treated as a people, and the little value set upon them, are noticed. None ever hardened his heart against God or his church, and prospered long.
