Yea, the fir trees rejoice at thee - They join with the inhabitants of the nations in rejoicing at thy downfall - for they now, like those inhabitants, are suffered to remain undisturbed. (On the word rendered "fir trees," see the notes at Isaiah 1:29.) It is evident that a species of evergreen is meant; and probably some species that grew in Syria or Palestine. The idea is plain. The very forest is represented as rejoicing. It would be safe from the king of Babylon. He could no longer cut it down to build his palaces, or to construct his implements of war. This figure of representing the hills and groves, the trees, the mountains, and the earth, as exulting, or as breaking forth into joy, is common in the Scriptures:
Let the heavens rejoice, and let the earth be glad;
Let the sea roar, and the fulness thereof.
Let the field be joyful, and all that is therein:
Then shall all the trees of the wood rejoice
Before the Lord.
Psalm 96:11-13.
Let the floods clap their hands.
Let the hills be joyful together
Before the Lord.
Psalm 98:8-9.
Praise the Lord from the earth,
Ye dragons and all deeps;
Fire and hail; snow and vapor;
Stormy wind fulfilling his word:
Mountains and all hills;
Fruitful trees and all cedars.
Psalm 148:7-12.
(Compare 1-Chronicles 16:31; Habakkuk 3:10-11.)
The cedars of Lebanon - (note, Isaiah 10:34). The cedars of Lebanon were much celebrated for building; and it is not impossible that the king of Babylon had obtained timber from that mountain with which to construct his palaces at Babylon. They are now represented as rejoicing that he is fallen, since they would be safe and undisturbed. A similar figure of speech occurs in Virgil, "Ecl." v. 68:
Peace, peace, mild Daphnis loves; with joyous cry.
The untill'd mountains strike the echoing sky;
And rocks and towers the triumph spread abroad -
'A god! Menalcas! Daphnis is a god!'
Wrangham
It is a beautiful figure; and is a fine specimen of the poetry of the Hebrews, where everything is animated, and full of life.
Since thou art laid down - Since thou art dead.
No feller - No one to cut us down. Jowett ("Chris. Res.") makes the following remarks on this passage on his visit to Lebanon: 'As we passed through the extensive forest of fir trees situated between Deir-el-Karat and Ainep, we had already heard, at some distance, the stroke of one solitary axe, resounding from hill to hill. On reaching the spot, we found a peasant, whose labor had been so far successful, that he had felled his tree and lopped his branches. He was now hewing it in the middle, so as to balance the two halves upon his camel, which stood patiently by him waiting for his load. In the days of Hiram, king of Tyre, and subsequently under the kings of Babylon, this romantic solitude was not so peaceful; that most poetic image in Isaiah, who makes these very trees vocal, exulting in the downfall of the destroyer of nations, seems now to be almost realized anew - "Yea, the fir trees rejoice at thee, and the cedars of Lebanon, saying, Since thou art laid down, no feller is come up against us."'

Yea, the fir trees rejoice at thee, and the cedars of Lebanon,.... Which by, a prosopopoeia are represented as singing and rejoicing, as inanimate creatures often are in Scripture, these being now in no danger of being cut down, to make way for his armies; see Isaiah 37:34 or to furnish him with timber for shipping, or building of houses: or else these words are to be understood metaphorically of kings and princes of the earth, comparable to such trees, for their height, strength, and substance; see Zac 11:2 who would now be no longer in fear of him, or in subjection to him. So the Targum,
"the rulers also rejoiced over thee, the rich in substance said;''
not only the common people, the inhabitants of the earth, as before, but the princes of it rejoiced at his ruin; and so will the kings of the earth rejoice at the destruction of the whore of Rome, when they shall hate her, eat her flesh, and burn her with fire; though others, that have committed fornication with her, will lament her case, Revelation 17:16,
saying, since thou art, laid down; or "art asleep" (a); that is, dead; it being usual in the eastern nations to express death by sleep:
no feller is come up against us; or "cutter of wood", to whom the king of Babylon is compared, for cutting down nations, and bringing them into subjection to him, in whose heart it was to destroy and cut off nations, not a few; being as an axe in the hand of the Lord, whereby trees, large and high, were cut down; see Isaiah 10:5 but now, since this feller of wood was gone, the axe was laid aside, and broke to pieces, there was none to give the nations any disturbance; and so it will be when antichrist is destroyed, there will be no more persecution of the church and people of God.

the fir trees--now left undisturbed. Probably a kind of evergreen.
rejoice at thee-- (Psalm 96:12). At thy fall (Psalm 35:19, Psalm 35:24).
no feller--as formerly, when thou wast in power (Isaiah 10:34; Isaiah 37:24).
Hades (the Amenthes of Egypt), the unseen abode of the departed; some of its tenants, once mighty monarchs, are represented by a bold personification as rising from their seats in astonishment at the descent among them of the humbled king of Babylon. This proves, in opposition to WARBURTON [The Divine Legation], that the belief existed among the Jews that there was a Sheol or Hades, in which the "Rephaim" or manes of the departed abode.

The trees - Which were felled for the service of her pride and luxury, but now are suffered to stand.
