And I will send my fear before thee,.... What should cause fear among the nations of the land of Canaan; either the hornets mentioned in the next verse as the explanative of this; or the fame of his mighty works, which he had done for Israel in Egypt, at the Red sea, and in the wilderness; which struck the inhabitants of Canaan with such a panic, that they were ready to faint and melt away, and lost all courage, Jos 2:9. and will destroy all the people to whom thou shalt come; that is, the greatest part of them: and I will make all thine enemies turn their backs unto thee; flee away, not being able to face them and stand a battle, or, however, not stand it long, but run and make their escape: "or I will give thee the neck of them" (p); cause them to submit, to lay down their necks and be trampled upon; an expression denoting their subjection, and an entire conquest of them, see Psa 18:39. (p) "et dabo-cervicem", Pagninus, Montanus; "exponam tibi cervicem", Junius & Tremellius, Piscator; "ponam ad te cervicem", Drusius.
