Charles Ellicott Commentary Isaiah 24:6

"Therefore hath the curse devoured the earth, and they that dwell therein are found guilty: therefore the inhabitants of the earth are burned, and few men left." — Isaiah 24:6 (ASV)

Therefore has the curse ... —The definite article may be either generic, the curse which always follows on evil-doing, or, more specifically, the curse of the Book of the Covenant, as in Leviticus 26:0;Deuteronomy 28:0. The curse is personified as a beast of prey or a consuming fire, ready to devour (Genesis 4:11).

They who dwell there are desolate. —Better, bear their punishment, or are dealt with as guilty.

Are burned. —The word determines, perhaps, the sense of the word “devour” in the previous clause. The curse, the symbol of the wrath of Jehovah, is the consuming fire that burns.
