Matthew Poole and continuators on Exodus 10:13

13 And Moses stretched forth his rod over the land of Egypt, and the LORD brought an Eastwind upon the land, all that day, and all that night, and when it was morning, the East-wind brought the locusts.

Over divers parts of the Land, shaking his rod towards the several quarters of it.

Which in those parts is a most violent and pernicious wind, Exod. 14. 21. Numb. 11. 31. and a dry wind, and therefore fit for the ingendring of those Creatures. This wind brought them from Arabia, where they are in great numbers, as we have seen ver. 12. though God miraculously increased their numbers and their power of doing mischief.
