Joel 3:2

I will also gather all nations: in the type, it is not simply all nations, but all those nations that have with hostile minds oppressed and scattered Judah; in the antitype, it is all nations that have been enemies to Christ and the church. And will bring them down: this is spoken with respect to the low situation of the place, being a valley, and we descend into low parts; so here they are caused to go down into the valley of Jehoshaphat: much difficulty interpreters find in explaining this; we must look to it as a type to somewhat signified by it, and so apply it. The valley of blessing where Jehoshaphat discomfited mighty and numerous enemies, and then triumphed in God with praises to him, 2 Chronicles 20:22, &c.: so the whole church may be this valley of blessing, and in this God will judge the enemies of his people, and give them occasions of praising God for his righteous judgments; and Jerusalem his church shall see this, as the inhabitants of Jerusalem might see what is done in the valley of Jehoshaphat, if they would be at a little pains to go out of the city. Will plead with them; after the manner of a just and impartial judge I will debate my people's cause, and do them right. There; in midst of my church, signified by the valley of Jehoshaphat, the valley of the judgment of God. For my people; Judah, the two tribes, but, as in their history, bearing a type of the church of Christ. For my heritage Israel; purchased and possessed by me ever since they were brought out of Egypt; though many times invaded and injured by their unjust neighbours, who were so much their enemies because they were my peculiar people, and kept to my worship. Whom they have scattered among the nations; either by force driving them out of their habitations, or else carrying them into captivity, and dispersing them in their insolent humour, of which dispersion more follows, Joel 3:3,6,8. And parted my land; divided among themselves the land I gave to my people to hold immediately of me; so it was my land that they divided, their robbery and spoil was sacrilege. Such is the injustice and oppression of persecutors of the church now, and so God will judge them in due time.
