Why does it say "v'Gam Zeh"?
Rashbam: Also this is Ra'ah Cholah, like those who mentioned above.
Metzudas David: Above (12), it said that it is "Ra'ah Cholah" that "Osher Shamur li'V'alav l'Ra'aso." Also this is Ra'ah Cholah, that the wealth will not remain in his hand.
What is the meaning of "Kol Umas she'Ba"?
Rav Sadya Gaon, Rashbam: Like he came.
Rashi: Like the money came, so it left. Metzudas David - like it came with toil, so it goes away with toil, in an evil way.
What is the meaning of "u'Mah Yisron Lo she'Ya'amol la'Ru'ach"?
Rav Sadya Gaon, Metzudas David: What gain does he have, that he toiled for nothing?
Seforno: Part of the evil that occurs to the Ashir is that he does not acquire any perfection. When he goes to his permanent abode (death), he will not take with him anything that will help him. In his lifetime, he toiled only for temporary life, and does not acquire anything that will help him after death. Then, he will have eternal life or eternal destruction.
