Matthew Poole and continuators on Joel 2:9

9 They shall run to and fro in the city : they shall run upon the wall , they shall climb up upon the houses : they shall enter in at the windows like a thief .

This seems not proper to these insects which move forward, and alter not their course in such limited and streightned bounds as a City, but this well suits with souldiers that conquer a City, and search all places for plunder and prey.

In every City that they take;

To clear the wall of all the besieged who did defend it, to help up others that were s[illegible: 1 letter]aling the Wall, and to sieze Towers which were built upon the Wall; this is better fitted to souldiers that take a City then to locusts.

Either forsaken and shut fast up by the inhabitants before they left them, or houses defended by such as are in them, as is usual in Cities taken by assault.

Where they can find the first entrance, there they will through, and nothing shall keep them out.

Suddenly, unexpectedly, to spoil at least, if not to kill and destroy, locusts and souldiers will do this.

In this verse we must discern what is any whit proper to the locusts, and what is applicable more fitly to the Souldiers figured by them.
