John Gill's Exposition of the Whole Bible
Psalms 83:8
Assur also is joined with them,.... Before mentioned, or Assyria, though at so great a distance from Israel, and unprovoked by them: according to R. Joseph Kimchi, the sense is, that the Assyrians joined them, continuing in their wickedness, though their army had been destroyed by an angel in Hezekiah's time, of which they were unmindful; but this, as his son observes, makes this confederacy and war to be after the times of Hezekiah; whereas it was long before it: the Targum is,
"Sennacherib, king of Syria, is joined with them;''
and so some refer this to his invasion of Judea, and besieging Jerusalem, with an army consisting of many nations, in Hezekiah's time; but he was the principal there, and not an auxiliary, as here:
they have holpen the children of Lot; or were "an arm" h unto them, assisted and strengthened them: these were the Moabites and Ammonites, who were the principals in the war, and the rest auxiliaries, as it appears they were in the times of Jehoshaphat,
2 Chronicles 20:1, here were ten different nations, which joined in confederacy against the people of Israel; to which answer the ten horns of the beast, or ten antichristian kings, who agreed to give their kingdom to the beast, and to make war with the Lamb and his followers, Revelation 17:12, and it may be observed, that these were on all sides of the land of Israel; the Edomites, Ishmaelites, and Amalekites, were on the south; the Moabites, Ammonites, and Hagarenes, were on the east; the Assyrians on the north; and the Philistines, Gebalites, and Tyrians, on the west: so that Israel was surrounded on all sides with enemies, as the Lord's people are troubled on every side, 2 Corinthians 4:8, and so the Gog and Magog army, of which some understand this, will encompass the camp of the saints about, and the beloved city, Revelation 20:9.
Selah. Psalms 3:2.
