Charles Ellicott Commentary Psalms 102:26

"They shall perish, but thou shalt endure; Yea, all of them shall wax old like a garment; As a vesture shalt thou change them, and they shall be changed:" — Psalms 102:26 (ASV)

Perish. —Compared with man, the victim of incessant change and visible decay, the fixed earth and the uplifted mountains are often employed as symbols of endurance and perpetuity, but compared with God’s eternal existence, they are but like a vesture that wears out. The source of the image is Isaiah 51:6. (Compare to Isaiah 34:4.) For the use made of the passage in Hebrews 1:10; Hebrews 1:12, see New Testament Commentary. The terms employed for “garment” and “vesture” (beged, lebûsh) are synonyms for the outer cloak worn by the Jews. The imagery of the text no doubt supplied Goethe with the thought in his fine lines

“It is thus at the roaring loom of time I ply,
And weave for God the garment you see Him by!”

which in turn suggested to Carlyle the “Philosophy of Clothes.” “Why multiply instances? It is written, the heavens and the earth shall fade away like a vesture, which, indeed they are—the time vesture of the Eternal.”— Sartor Resartus, I. 11

It is interesting to think how the science of geology confirms the image of the psalmist, showing how time has been literally changing the so solid-seeming earth, stripping off the robe that covers the hills, to fold it down at some river mouth, or at the bottom of the ocean bed.
