Charles Ellicott Commentary Isaiah 5:24

"Therefore as the tongue of fire devoureth the stubble, and as the dry grass sinketh down in the flame, so their root shall be as rottenness, and their blossom shall go up as dust; because they have rejected the law of Jehovah of hosts, and despised the word of the Holy One of Israel." — Isaiah 5:24 (ASV)

Therefore as the fire devoureth. —Literally, the tongue of fire. The scene brought before us is—

1. that of a charred and burnt-up field, horrible and hideous to look upon ;
2. that of a tree decayed and loathsome.

The double imagery represents the end of the riotous mirth of the unjust judges.
