Albert Barnes Commentary Ezekiel 19:12

"But it was plucked up in fury, it was cast down to the ground, and the east wind dried up its fruit: its strong rods were broken off and withered; the fire consumed them." — Ezekiel 19:12 (ASV)

This is a dirge; and therefore that which is foreseen by the prophet, the capture and burning of Jerusalem, is described as already accomplished.
