וְהָיְתָ֤ה נִבְלָֽתְךָ֙ לְמַאֲכָ֔ל לְכָל־ע֥וֹף הַשָּׁמַ֖יִם וּלְבֶהֱמַ֣ת הָאָ֑רֶץ וְאֵ֖ין מַחֲרִֽיד׃
И туши твои будут пищей для всех птиц воздуха и для зверей земных, и некому будет отпугнуть их.
Chizkuni
ואין מחריד, “and there is no one to frighten them away.” No one will bother to bury these carcasses as the survivors have so many other problems to deal with. An alternate interpretation: no one will chase the vultures away.
Ibn Ezra
with none to frighten them off The implied object of the verb is the antecedent birds and beasts.
Rashbam
ואין מחריד; no one will chase away the vultures from consuming the dead bodies as there is no one left to bury them.
