The Locust Kings

Tomorrow morning, the study I lead will take up the prophet Joel.  As I was studying, I came across interesting commentary for chapter 1, verse 4:

What the cutting locust left,

the swarming locust has eaten.

What the swarming locust left,

the hopping locust has eaten,

and what the hopping locust left,

the destroying locust has eaten.

Both Jerome and Theodore of Mopsuestia equate the four locusts with four distinct kings that came against national Israel: Tiglath-Pileser, Shalmaneser, Sennacherib, and Nebuchadnezzar.  That seems reasonable.  My prior instruction on this passage led me to think that this passage described the destruction under the last king mentioned.
