What is "Meshiv Yaga"?
Rashi: What he stole.
What do we learn from "v'Lo Yivla [k'Cheil Temuraso]"?
Rashi: Even if he puts what he stole in his mouth, he will not swallow it (all will return to the original owner).
Seforno: It is taken back from him, and his sons after him will not get it.
Metzudas David: Like the magnitude of his wealth, so will be his poverty.
Malbim: He does not swallow (benefit) from the delicacies as much as the toil he gave for them.
Why did he add "v'Lo Ya'alos"?
Rashi: He will not rejoice. Ya'alos, Ya'aloz and Ya'alotz are interchangeable.
Malbim: The Simchah he has from the delicacies is nothing compared to his toil to get them. therefore, this is not success.
