John Gill Commentary Ezekiel 15:6

"Therefore thus saith the Lord Jehovah: As the vine-tree among the trees of the forest, which I have given to the fire for fuel, so will I give the inhabitants of Jerusalem." — Ezekiel 15:6 (ASV)

Therefore thus says the Lord God. Now follows the application of the simile: as the vine tree among the trees of the forest, which I have given to the fire for fuel; to be burnt, as other trees of the forest are, and along with them. So will I give the inhabitants of Jerusalem; to be destroyed along with other nations by the Chaldeans; they being no better, but as bad, if not worse, like wild vines among forest trees; and therefore must fare no better. This was the decree and determination of the Lord.
