ALL OF YISRAEL ARE BNEI MELACHIM
Why are Yisrael called Bnei Melachim?
Maharal: An old Sefer says that this merely comes to explain "Banim Atem la'Shem Elokeichem" and "Bnei Kel Chai." Yisrael are Bnei Melachim, and not sons of the 10 rulers among the stars, and not Bnei Sarim and Moshelim - "Ki Chelek Hash-m Amo."
What is the meaning of 'princes may rub rose oil on their wounds, for they anoint themselves with it on weekdays'?
Rashi: They may anoint their wounds with it on Shabbos, and we do not decree due to grinding ingredients, since they anoint with it on weekdays even when they have no wound, so it is not evident that it is for Refu'ah.
Rav Elyashiv: Because they anoint with it for pleasure, even if they intend for Refu'ah on Shabbos, it is permitted, for it is like a food that healthy people eat. If a poor Yisrael does so, even though it is clearly for Refu'ah, since he is a Ben Melech, it is considered that he does so for pleasure, and it is permitted.
What is the consequence of 'any Yisrael is proper for such a garment'?
Rav Elyashiv: Surely, it is proper that he pay his debt, if not with money, at least with Shaveh Kesef, even the expensive garment itself. Beis Din cannot take it for him, for it is considered proper for him.
