11:1-3 In figurative expressions, that destruction of Jerusalem, and of the Jewish church and nation, is foretold, which our Lord Jesus, when the time was at hand, prophesied plainly and expressly. How can the fir trees stand, if the cedars fall? The falls of the wise and good into sin, and the falls of the rich and great into trouble, are loud alarms to those every way their inferiors. It is sad with a people, when those who should be as shepherds to them, are as young lions. The pride of Jordan was the thickets on the banks; and when the river overflowed the banks, the lions came up from them roaring. Thus the doom of Jerusalem may alarm other churches.
2. fir tree … cedar—if even the cedars (the highest in the state) are not spared, how much less the fir trees (the lowest)!
forest of … vintage—As the vines are stripped of their grapes in the vintage (compare Joe 3:13), so the forest of Lebanon "is come down," stripped of all its beauty. Rather, "the fortified" or "inaccessible forest" [Maurer]; that is, Jerusalem dense with houses as a thick forest is with trees, and "fortified" with a wall around. Compare Mic 3:12, where its desolate state is described as a forest.
