The Prophet proceeds with the same subject, -- that God will at length become an avenger of the wrongs of his people, when they shall be unjustly harassed by profane men. We indeed know that God does not immediately succor his servants but rests as though he did not regard their troubles; but this he does to try their patience; and then at a suitable time he declares that he had not been indifferent, but had noticed the evils done to them, and deferred punishment until the wickedness of his enemies had been completed. So he says now, that God will at length be the defender of his people against all the nations assembled from every quarter in the valley of Jehoshaphat. Of this valley we have said enough already. But the chief thing is, that the afflictions of the Church shall not go unpunished; for God at the right time will ascend his tribunal, and cause all nations from every part of the earth to assemble and to be there judged. Now it follows --

Let the pagan be awakened - This emphatic repetition of the word, "awaken," seems intended to hint at the great awakening, to Judgment , when they "who sleep in the dust of the earth shall awake, being awakened" from the sleep of death. Another word is used of "awakening" . On the destruction of antichrist it is thought that the general Judgment will follow, and "all who are in the graves shall hear the voice of the Son of Man and shall come forth" John 5:27-29 : They are bidden to "come up" into the valley of Jehoshaphat , "for to come into the presence of the most High God, may well be called "a coming up." For there will I sit to judge all the pagan round about," (again literally "from round about,) from every side," all nations from all the four quarters of the world. The words are the same as before. There "all nations from every side" were summoned to come, as they thought, to destroy God's people and heritage. Here the real end is assigned, for which they were brought together, for God would sit to judge them. In their own blind will and passion they came to destroy; in God's secret overruling Providence, they were dragged along by their passions - to be judged and to be destroyed. So our Lord says, "When the Son of Man shall come in His Glory, and all the Holy Angels with Him, then shall He sit on the throne of His Glory and before Him shall be gathered all nations" Matthew 25:31-32. Our Lord, in that He uses words of Joel, seems to intend to direct our minds to the prophet's meaning. What follows are nearly His own words;

Let the heathen be wakened - The heathen shall be wakened.
The valley of Jehoshaphat - Any place where God may choose to display his judgments against his enemies.

Let the Heathen be awakened, and come to the valley of Jehoshaphat,.... That is, let the enemies of Christ and his church be aroused from that state of security in which they are, and prepare for their own defence; for in such a state the antichristian powers will be before their destruction; see Revelation 18:7; let them bestir themselves, and exert all the rigour and strength they have; let them come in high spirits against the people of God; let them invade the holy land, and come even to the valley of Jehoshaphat; and, when come thither, let them, descend into the place appointed for their ruin: the land of Judea being said to be higher than other countries, going to it is generally expressed by going up to it; otherwise it is more usual to say that men go down a valley than come up to it; and, mention being made again of this valley, shows that the same thing is referred to here as in Joel 3:2; these words are said in answer to the petition in Joel 3:11; for they are spoken by the Lord, as appears by what follows:
for there will I sit to judge all the Heathen round about; thither gathered together from all parts: the allusion is to a judge upon the bench, sitting to hear and try causes, and pass a definitive sentence; and here it signifies the execution of that sentence; such a pleading the cause of his people, as to take vengeance and inflict just punishment upon their enemies; see Psalm 9:4.

See Joel 3:2.
judge all the heathen round about--that is, all the nations from all parts of the earth which have maltreated Israel; not merely, as HENDERSON supposes, the nations round about Jerusalem (compare Psalm 110:6; Isaiah 2:4; Micah 4:3, Micah 4:11-13; Zephaniah 3:15-19; Zac 12:9; Zac 14:3-11; Malachi 4:1-3).

The heathen - The several nations in their appointed time, perhaps the Assyrians first under Salmaneser, next under Sennacherib, both of whom came up to the valley of Jehoshaphat. For there - In the midst of my people to plead with, condemn and punish the heathen round about Judea.
