Why does it specify "v'Kalu mi'Nemerim"?
Malbim: A Nemer (tiger) is very fast.
What is "Chadu"?
Radak: It is Chidud and Charifus (sharpness, astuteness).
Why does it specify "Ze'evi Erev"?
Radak: Wolves go out in the evening to tear.
Malbim: They are sharper and wilder than forest wolves, which are very wild.
What is the meaning of "u'Fashu Parashav"?
Rashi, Targum Yonasan: Its cavalry increased. Radak ? this is like I explained "Nafoshu Amecha" (refer to Nachum 3:8:3:2).
Malbim: Normally, cavalry fear to ride on these [very fast] horses. Even so, there will be many.
Why does it mention "u'Farashav me'Rachok Yavo'u"?
Malbim: Even though they will be tired after a long journey, they will not rest. "They will fly like a Nesher?"
What do we learn from "Chash Le'echol"?
Radak: It flies quickly to a carcass that it sees from afar 1 . The Nesher flies higher and faster than other birds. Therefore, it mentions Nesher.
Radak citing Targum Yonasan: It flies to eat.
Malbim: They will fly like a Nesher that is quick to eat ? immediately when they come, they will fight, conquer and take spoils.
Radak holds that Nesher eats Neveilos. Mishlei (30:17) and Iyov (39:27-30) support this. Tosfos (Chulin 63a DH Netz) - people say that Nesher is an eagle. It is not; eagles have an Etzba Yeserah; a Nesher does not! R. D. T. Hofman (Vayikra 11:13, cited in Daf Al ha'Daf Chulin 61a) ? Mendelzon says that our eagles do not have one.
