2. The sitting of this court for judgment. They shall all be gathered (v. 2), that those who have combined together against God's people, with one consent (Ps. lxxxiii. 5), may together receive their doom. They shall be brought down into the valley of Jehoshaphat, which lay near Jerusalem, and there God will plead with them, (1.) Because it is fit that criminals should be tried in the same country where they did the fact. (2.) For their greater confusion, when they shall see that Jerusalem which they have so long endeavored and hoped for the ruin of, in spite of all their rage, made a praise in the earth. (3.) For the greater comfort and honor of God's Jerusalem, which shall see God pleading their cause. (4.) Then shall be re-acted what God did for Jehoshaphat when he gave him victory over those that invaded him, and furnished him and his people with matter of joy and praise, in the valley of Berachah. See 2 Chron. xx. 26. (5.) It was in this valley of Jehoshaphat (as Dr. Lightfoot suggests) that Sennacherib's army, or part of it, lay, when it was destroyed by an angel. They came together to ruin Jerusalem, but God brought them together for their own ruin, as sheaves into the floor, Mic. iv. 12.
