Matthew Poole and continuators on Exodus 8:3

3 And the river shall bring forth frogs abundantly, which shall go up and come into thine house, and into thy bed chamber , and upon thy bed, and into the house of thy servants, and upon thy people, and into thine ovens, and into thy kneading-troughs.

Under which are comprehended all other rivers, streams and ponds, as appears from ver. 5. But the river Nilus is mentioned, because God would make that an instrument of their misery, in which they most gloried, Ezek. 29. 3. and to which they gave divine honours, and which was the instrument of their cruelty against the Israelites, chap. 1. 22.

Either because God made the doors and windows to flie open, which it is easie to believe concerning God, seeing this hath been many times done by evil Angels; or because whensoever men entred into any house or any room of their house, which their occasions would oft force them to do, the frogs, being always at their heels in great numbers, would go in with them. This plague was worse than the former, because it was more constant and more general; for the former was onely in the waters, and did onely molest them when they went to drink or use the water, but this infected all liquors and all places, and at all times, and annoyed all their sences with their filthy substance and shape and noise and stink, and mingled themselves with their meats and [illegible: 1+ letters]auces and drinks, and crawling into their bed[illegible: 1+ letters] made them restless. And many of them probably were of a more ugly shape and infectious nature than ordinary.
