Exodus 10:7 - Joseph Benson’s Commentary on the Old and New Testaments

Pharaoh's servants His nobles and counsellors; said, How long shall this man be a snare unto us? That is, lay before us the occasion of our falling into one calamity after another. To the impenitent the punishment of sin, not the sin which is punished, is the cause of their sorrow. Knowest thou not yet that Egypt is destroyed? It was so in a great degree by these repeated and very destructive plagues.
