Adam Clarke on Matthew 24:28

For wheresoever the carcass is - Πτωμα, the dead carcass. The Jewish nation, which was morally and judicially dead.

There will the eagles - The Roman armies, called so partly from their strength and fierceness, and partly from the figure of these animals which was always wrought on their ensigns, or even in brass, placed on the tops of their ensign-staves. It is remarkable that the Roman fury pursued these wretched men wheresoever they were found. They were a dead carcass doomed to be devoured; and the Roman eagles were the commissioned devourers. See the pitiful account in Josephus, War, b. vii. c. 2, 3, 6, 9, 10, and 11.
