SEV Biblia, Chapter 20:21
No quiso, pues , Edom dejar pasar a Israel por su término, y así se apartó Israel de él.
Clarke's Bible Commentary - Numbers 20:21
Verse 21. Thus Edom refused to give Israel passage through his border] Though every king has a right to refuse passage through his territories to any strangers; yet in a case like this, and in a time also in which emigrations were frequent and universally allowed, it was both cruelty and oppression in Edom to refuse a passage to a comparatively unarmed and inoffensive multitude, who were all their own near kinsmen. It appears however that it was only the Edomites of Kadesh that were thus unfriendly and cruel; for from Deut. ii. 29 we learn that the Edomites who dwelt in Mount Seir treated them in a hospitable manner. This cruelty in the Edomites of Kadesh is strongly reprehended, and threatened by the Prophet Obadiah, Obidiah 10, &c.
Matthew Henry Commentary
Verses 14-21 - The nearest way to Canaan from the place where Israel encamped, wa through the country of Edom. The ambassadors who were sent returne 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 thi jealousy. But Esau hated Jacob because of the blessing; and now the hatred revived, when the blessing was about to be inherited. We mus not think it strange, if reasonable requests be denied by unreasonabl men, and if those whom God favours be affronted by men.
