Rejoice not, all of Philistia, because the rod of him that struck you is broken: for out of the serpent's root shall come forth an adder, and his fruit shall be a fiery flying serpent.

Bird. Ezechias will openly attack thee, 4 Kings xviii. 8. (Calmet)
Protestants, "shall be a fiery flying serpent "(Haydock) like that erected by Moses, Numbers xxi. 9. Sennacherib and Assaraddon shall lay waste Philistia, ver. 31., and chap. xx. 1. (Calmet)
Though Achaz be dead, Ezechias and Ozias will destroy more of that nation, 4 Kings xviii. 8., and 2 Paralipomenon xxvi. (Worthington)
But because this Leviathan is called in another place not merely a serpent but also a flying serpent, because he rules over unclean spirits or reprobate people, as Isaiah says, “Out of the serpent’s root shall come forth a flying serpent,” we must attentively observe how a basilisk destroys, that by the doings of the basilisk, his malice may be more plainly made known to us. For a basilisk does not destroy with its bite but consumes with its breath. It often also infects the air with its breath and withers with the mere blast of its nostrils whatever it has touched, even when placed at a distance. - "Morals on the Book of Job 6.33.62"
