Commentaries:
Adam Clarke
All the waters - were turned to blood - Not merely in appearance, but in reality; for these changed waters became corrupt and insalubrious, so that even the fish that were in the river died; and the smell became highly offensive, so that the waters could not be drank; Exodus 7:21.
