R. Yonathan says: "and I will skip over you." I will be compassionate to you, but not to the Egyptians. I might think that an Egyptian in a Jewish house would be rescued. It is, therefore, written "and I will skip over you"—over you, but not over the Egyptians. If an Israelite were in an Egyptian house, I might think he would be smitten together with them. It is, therefore, written (Exodus, Ibid.) "and there will be no destroying plague on you when I smite the land of Egypt." It will not be on you, but it will be on the Egyptians.
