כִּ֚י בַּיּ֣וֹם הַה֔וּא יִמְאָס֗וּן אִ֚ישׁ אֱלִילֵ֣י כַסְפּ֔וֹ וֶאֱלִילֵ֖י זְהָב֑וֹ אֲשֶׁ֨ר עָשׂ֥וּ לָכֶ֛ם יְדֵיכֶ֖ם חֵֽטְא׃
For in that day they shall cast away every man his idols of silver, and his idols of gold, Which your own hands have made unto you for a sin.
Ibn Ezra on Isaiah
חטא For a sin; for a sin κατ ἐξοχήν, a sin that surpasses all others.
