What is "b'Nafsho"?
Rashi: In Himself. Radak - this is like "Bi Nishbati" (Bereishis 22:16). A person, he and his Nefesh are different matters. Hashem is not like this, just Dibrah Torah k'Leshon Bnei Adam (the Torah speaks the way people do). The same applies to "v'Nafsho Iveso va'Ya'as" (Iyov 23:13).
What is the meaning of "Ki Im"?
Rashi: In truth.
Radak: It is an expression of a Shevu'ah.
What is the meaning of "Mileisicha Adam"?
Rashi: I will fill you with camps of nations numerous like locusts. Radak - we find "Chedei Arbeh la'Rov" (Shoftim 6:5). Here, the past tense is used to refer to the future.
What is the meaning of "v'Anu Alecha Heidad"?
Rashi: They will raise their voices over you.
Radak: They will scream 'Heidad', like "Heidad k'Dorchim Ya'aneh" (30:25).
