What are "Eleh"?
Rashi: Those whom he gathered to himself to serve him.
Radak: These nations that he gathered to himself.
Malbim: All the nations that he conquered.
Why will they make a Mashal about him?
Radak: When his fall will come, they will rejoice over this.
What is the meaning of "u'Melitzah Chidos Lo"?
Rashi: They make metaphors and riddles about he must. "Lo" is like 'Alav'.
Malbim: Melitzah is the solution of the Mashal; it is said like a riddle.
What is the significance of "Hoy ha'Marbeh Lo Lo"?
Rashi: This is the metaphor. Woe to one who increases wealth and kingship, and it is not for him, for the kings of Madai will come and take everything.
Radak: Woe to this one who gathers much property that is not his ? he plunders many nations.
Malbim: This is the Mashal ? a man who always borrows from others with Ribis, and he does not borrow for his own needs, rather, for others. He accepts on himself to pay the principal and Ribis. He is Marbeh (borrows with Ribis) not for himself.
Malbim (8): The Nimshal is, you plunder many nations, and it will not be for you. It is guarded for Madai and Paras, who will take it from you, and you will need to pay.
Why does it say "Ad Masai"?
Rashi: Until when will he increase?
Radak: Does he think that it will stand forever in his hand and in his seed's hand?
Radak citing his father: Does he not realize that in the end, he will go to the grave?
Radak: Until when do you make great liability on yourself?
Malbim: Is there no limit until when he will always borrow and not pay?!
What is the meaning of "u'Machbid Alav Avtit"?
Rashi: He merely makes the burden of sin heavy upon himself like an Av of Tit. Av is an expression of a heavy beam, like we find in Yechezkel's description of the [future] Mikdash "Tzal'os ha'Bayis veha'Ubim", "v'Av Etz" (Yechezkel 41:26, 25).
Radak: He makes heavy on himself much money, which is like Tit Av (thick mud). It weighs on his body, which is mud and earth. Also his money will be so! Avtit is one word, but it is explained like two words. Avtit is like Tit Av (reversed); also "Kol Rabim Amim" (Tehilim 89:51) means Amim Rabim, "bi'Yrakrak Charutz" (ibid. 68:14) is like b'Charutz Yerakrak.
Radak citing ha'Nagid: He will increase to build a Mishkan, and it will be save him.
Radak citing his father: Thick mud will be heavy on his grave.
Malbim: He accepts upon himself the Avot (security) and the debt that he is liable to pay to the one who Avat (lent) to him.
