הַשְּׂמֵחִ֖ים לְלֹ֣א דָבָ֑ר הָאֹ֣מְרִ֔ים הֲל֣וֹא בְחָזְקֵ֔נוּ לָקַ֥חְנוּ לָ֖נוּ קַרְנָֽיִם׃
Ye that rejoice in a thing of nought, That say: ‘Have we not taken to us horns by our own strength?’
Rashi on Amos
over a thing of naught—Over their greatness and their wealth, which is nought, since it will not endure.
Rashi on Amos
horns—Strength and might to gore the poor and needy with the horns.
