Matthew Poole and continuators on Joel 2:4

4 The appearance of them is as the appearance of horses , and as horsemen, so shall they run .

Their carriage for fierceness, agility and irresistibleness, is like that of horses trained up to the Wars, of which Iob 39.20.

This gives light to the former expression, and by it we see these locusts are not resembled to the horse for shape, but for their nimbleness in motion. And as were these Types, so should the Armies which were typified be also.
