Exodus 7:18
Ver. 18. And the fish that is in the river shall die,.... Their element being changed, and they not able to live in any other but water:
and the river shall stink; with the blood, into which it should be congealed, and with the putrefied bodies of fishes floating in it:
and the Egyptians shall loath to drink of the water of the river; the very colour of it, looking like blood, would set them against it, and create a nausea in them; or "shall be weary" {h}, tired of drinking it in a little time, through the loathsomeness of it; or be weary in digging about it, Ex 7:24 to get some clear water to drink of; or in seeking to find out ways and methods to cure the waters, that so they might be fit to drink of, as Jarchi interprets it.
