Deuteronomy 7:15

The diseases of Egypt Such as the Egyptians were infected with, either commonly, or miraculously. It seems to refer not only to the plagues of Egypt, but to some other epidemic diseases, which they remembered to have prevailed among the Egyptians, and by which God had chastised them for their national sins. The leprosy, and other cutaneous distempers, were frequent in Egypt. The Scriptures also mention the botch of Egypt, as a disease common in that country, Deuteronomy 28:27. Diseases are God's servants, which go where he sends them, and do what he bids them.
