מֵחֲמַ֛ס אָחִ֥יךָ יַעֲקֹ֖ב תְּכַסְּךָ֣ בוּשָׁ֑ה וְנִכְרַ֖תָּ לְעוֹלָֽם׃
네가 네 형제 야곱에게 행한 포학을 인하여 수욕을 입고 영원히 멸절되리라
Rashi
Because of the violence of your brother Jacob—Because of the violence you inflicted upon Jacob.
Tze'enah Ure'enah
“For the outrage to your brother Jacob, disgrace will cover you, etc.” [1:10]. Because you Edom behaved unjustly to your brother Jacob, therefore you will be covered with shame and disgrace and will be cut off forever. Edom did much evil to Israel in the destruction of the second Temple.5Radak, Obadiah, 1:10.
