Of course, here, we don’t mean the physiological health problems of people wandering in the desert. We are talking only about the desires of a person that he corrects on these levels.
Clothing is a screen that only a man can create and use. The lower desires don’t feel shame or need covering. Their coating is limited to fur, and a person must have a special cover that he himself creates.
The normal cover is made from animal skin. The skins are considered clothing, and in addition, tents can be constructed from them, for example, such as Bedouins erect for themselves. It means that this is the natural clothing and the natural home for a person.
There are clothes of a higher rank. It is wool of animal origin. Only this is considered real clothing, unlike all other materials.
Question: What is meant by “your clothing did not wear out upon you?”
Answer: It means that you constantly were adding screens on the desires that appear in you. Clothing is a screen for the body, for the desires.
“Nor did your foot swell” means that you definitely were mastering such desires that worked together with your head.
The foot symbolizes the end of the spiritual Partzuf, NHY (Netzah, Hod, Yesod). It is the biggest problem in the spiritual body because there are the biggest, deepest, lowest, and most material desires in it.
They are fulfilled only after they rise and become included in the body. When a person doesn’t stand but sits with his legs bent under him, then he receives fulfillment, or even when he lies and his head, body, and feet are on the same spiritual level.
In other words, “nor did your foot swell” means that all parts of a person worked in harmony, in unison.
