וְאַל־תֵּ֤רֶא בְיוֹם־אָחִ֙יךָ֙ בְּי֣וֹם נָכְר֔וֹ וְאַל־תִּשְׂמַ֥ח לִבְנֵֽי־יְהוּדָ֖ה בְּי֣וֹם אָבְדָ֑ם וְאַל־תַּגְדֵּ֥ל פִּ֖יךָ בְּי֥וֹם צָרָֽה׃
你本不該在你兄弟遭難的日子，就是他被交在仇敵手中的日子袖手旁觀；你本不該在猶大人滅亡的日子幸災樂禍；你也不該在他們遭難的日子張口說狂傲的話。
Rashi
And you should not have looked on the day of your brother—You should not have looked and stood from afar.
Rashi
on the day of his being delivered Heb. נָכְרוֹ. On the day of his being delivered into the hands of the heathens. And so does Scripture state concerning Saul: (I Sam. 23:7) “נִכַּר אֹתוֹ אֱלֹהִים בְּיָדְי,” “He has delivered him into my hand.”
Tze'enah Ure'enah
“You should not have gloated over your brother, on the day of his misfortune” [1:12]. You Edom should not have looked at the misfortune of your brother on the day that he was taken to a foreign land. You should not have rejoiced over the children of Judah on the day of their defeat.
