מֵחֲמַ֛ס אָחִ֥יךָ יַעֲקֹ֖ב תְּכַסְּךָ֣ בוּשָׁ֑ה וְנִכְרַ֖תָּ לְעוֹלָֽם׃
因你向你兄弟雅各所行的強暴，羞愧必遮蓋你，你也必被剪除，直到永遠。
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.
