Rashi on Deuteronomy 28:22/רש"י על דברים כ״ח:כ״ב

1בשחפת — This is a disease whereby one’s flesh becomes worn away and swollen.

2ובקדחת AND WITH FEVER — The word is similar in meaning to the verb in (Deuteronomy 32:22) “For a fire burns (קדחה) in My nostrils”. It is the heat felt by sick people, mal du feu in old French, which is a very high temperature.

3ובדלקת — This is a fever even hotter than קדחת. — All these terms denote different kinds of diseases, but of a similar character.

4ובחרחר — a disease that makes one burning hot inside the body, so that one is continually thirsting for water; in old French astrandement. The word is of the same meaning as the verbs in (Job 30:30) “My bones are burnt (חרה) because of heat”, and in (Jeremiah 6:29) “The bellows are burnt (נחר) by the fire”.

5ובחרב AND WITH THE SWORD — i.e. He will bring hostile troops against you.

6ובשדפון ובירקון AND WITH BLASTING AND WITH MILDEW — these are diseases that afflict grain which is yet in the field (yet growing).

7שדפון is the hot east-wind, hale in old French

8ירקון is drought. The symptoms are that the surface of the grain becomes pale and ultimately turns yellow; chaume in old French

9עד אבדך — The Targum renders this by עד דתיבד, meaning “until you perish”, i.e. until you will perish on your own.
