Why does it say "u'Min ha'Maskilim Yikashlu"?
Malbim: Even Chachamim will stumble, e.g. R. Akiva, who carried Bar Koziva's weapons (he thought that he is Mashi'ach).
What do we learn from "Yikashlu Litzrof Bahem"?
Rashi: They will stumble in calculation of Ketzim.
Why does it say "Levarer v'Lalben"?
Rashi: They will strive to clarify to calculate correctly, but they will err.
Malbim: They will purify and whiten the sins of Yisrael.
What will be "Ad Es Ketz"?
Ibn Ezra: They will stumble in every Dor until Mashi'ach.
Malbim: After the great Chasidim are killed, the sins of the generations were atoned for.
What do we learn from "Ki Od la'Mo'ed"?
Malbim: So will happen many times until the time of Ge'ulah. Every decree of Shmad (against Mitzvos), great Kedoshim were killed, and there was help lest Yisrael be totally eradicated.
