SEV Biblia, Chapter 20:20 Y él respondió: No pasarás. Y salió Edom contra él con mucho pueblo, y mano fuerte.
John Gill's Bible Commentary Ver. 20. And he said, thou shall not go through , etc.] Which is an absolute and peremptory denial: and Edom came out against him with much people, and with a strong hand ; the king raised the militia of his country, and came at the head of a powerful army to hinder their passing into it; being fearful and jealous, lest such a large body as they were should seize on his country, or spoil it, not relying on their promises; and this might arise also from the old grudge of Esau against Jacob, and which continued in his posterity, and might now be revived upon their going to Canaan to possess the earthly blessing conferred on Jacob and his seed: however, it seems, though the Edomites would not let Israel pass through their country, yet they furnished them with food and drink for their money, ( Deuteronomy 2:28,29).
Ver. 21 Thus Edom refused to give Israel passage through his country , etc.] Notwithstanding their near relation to each other, and the fair promises Israel made: wherefore Israel turned away from him : patiently bearing the refusal, and not resenting it; being ordered, as the Targum of Jonathan expresses it, by the Word of heaven, not to make war with them, because the time was not yet come to take vengeance on Edom by their hands; and to the same purpose the Targum of Jerusalem.
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.
