And it is not the custom of the language to say that a man is תחת המכסה (under the covering). It should say, המכסה הוא על האדם (the covering is on the man); as it is proper to say that the secondary is on the primary, not that the primary is under the secondary. And from this, it is proven that when it is written הנוגע בכל אשר יהיה תחתיו (And whosoever touches any thing that was under him)⁷⁵², it is referring to the saddle.

And moreover when it is written נגע צרעת כי תהיה באדם (When the plague of leprosy is in a man)⁷⁵³, it was proper to say אדם כי יהיה בו נגע צרעת, and there is a homiletical interpretation.

And it is typical for the language to say יצא לחפשי (he shall go out free)⁷⁵⁴ or לחפשי ישלחנו (he shall let him go free)⁷⁵⁵. And the language חופשה לא ניתן לה (nor was freedom given to her)⁷⁵⁶, is talking about a bill of release.

According to the sages of blessed memory, the reason why Leviticus 13:9 saysנגע צרעת כי תהיה באדם*(When the plague of leprosy in a man) instead of אדם כי יהיה בו נגע צרעת is to teach that the law applies even when the plague is all over a man⁷⁵⁷.*
