What is the meaning of "b'Lo Yomo Timalei"?
Rashi: The replacement will reach its fullness, and cease to grow and succeed. "Va'Yimla'u Lo Arba'im Yom" means that they finished.
Ibn Ezra: Most explain that the Aleph in Timalei is in place of a Lamed. This is like "v'Katafta Melilos" (sheaves), 'Molelo (he rolls it) and smells it' (Nidah 58b).
Malbim: It will be cut off before its time. "Timalei" is based on Melol; the Aleph is in place of the doubled Lamed, like "Baz'u Neharim Artzo" (is like Bazezu).
What is "Kipaso"?
Rashi: The bending of its branches. All the branches of a tree resemble a Kipah (dome).
Ibn Ezra: This is like "Kipah v'Agmon" (i.e. the root - Ibn Ezra Yeshayah 9:13).
Malbim: It is the branches and leaves, which cover the fruit - a metaphor for his acquisitions and wealth.
