(Devarim, Ibid. 24) "mezei with hunger and embattled by reshef": They will be hairy with hunger and strewn about the streets, as it is written (Jeremiah 14:16) "And the people to whom they prophesy will be strewn about in the streets of Jerusalem."
"and cut down by Meriri" (a demon) — whence it is derived that whoever is invested by a demon becomes rebellious ("mored").
"And the tooth of beasts I will send against them": His beast will bite and raise (in the victim) a fatal ulcer. Indeed, we have been witnesses to sheep biting and killing.
