Verse 18. - And Edom said... Thou shalt not pass by me. This was the first of a series of hostile acts, prompted by vindictive jealousy, which brought down the wrath of God upon Edom (compare the prophecy of Obadiah). See, however, on Deuteronomy 2:29.

20:14-21 The nearest way to Canaan from the place where Israel encamped, was through the country of Edom. The ambassadors who were sent returned with a denial. The Edomites feared to receive damage by the Israelites. And had this numerous army been under any other discipline than that of the righteous God himself, there might have been cause for this jealousy. But Esau hated Jacob because of the blessing; and now the hatred revived, when the blessing was about to be inherited. We must not think it strange, if reasonable requests be denied by unreasonable men, and if those whom God favours be affronted by men.And Edom said unto him,.... The king of Edom replied to Israel, represented by the messengers sent in their name:

thou shall not pass by me; through my country:

lest I come out against thee with the sword; or with those that use the sword, as the Targums of Onkelos and Jonathan; that is, with an army of soldiers with their drawn swords in their hands, to slay them as enemies.
