In enumerating the "curses" that would occur if we do not perform mitzvoth, Devarim 28:61 says:
"גַּם כָּל־חֳלִי וְכָל־מַכָּה אֲשֶׁר לֹא כָתוּב בְּסֵפֶר הַתּוֹרָה הַזֹּאת יַעְלֵם ה' עָלֶיךָ עַד הִשָּׁמְדָךְ׃
Moreover, the LORD will bring upon you all the other diseases and plagues that are not mentioned in this book of Teaching, until you are wiped out.
Has any commentary or other source mentioned what this / these are? There are numerous illnesses that the Torah doesn't mention - smallpox, polio, pneumonia etc. It could be any of these or others. If one had one of these, is it a fulfillment of this verse?
The Torah mentions all kinds of other illnesses - 3 of them, alone, are mentioned in Devarim 28:20. Moreso, in verse 20, it says, "until they destroy you." - It seems that means death. Even if not, if you've already been destroyed, physically, what would these additional "non-written" illnesses do?
Why did the Torah opt not to mention these illnesses? What's unique about them?
