וְאֶֽת־הַֽמִּזְבְּח֡וֹת אֲשֶׁ֣ר עַל־הַגָּג֩ עֲלִיַּ֨ת אָחָ֜ז אֲשֶׁר־עָשׂ֣וּ ׀ מַלְכֵ֣י יְהוּדָ֗ה וְאֶת־הַֽמִּזְבְּחוֹת֙ אֲשֶׁר־עָשָׂ֣ה מְנַשֶּׁ֔ה בִּשְׁתֵּ֛י חַצְר֥וֹת בֵּית־יְהוָ֖ה נָתַ֣ץ הַמֶּ֑לֶךְ וַיָּ֣רָץ מִשָּׁ֔ם וְהִשְׁלִ֥יךְ אֶת־עֲפָרָ֖ם אֶל־נַ֥חַל קִדְרֽוֹן׃
Rashi on II Kings
He quickly removed them from there. And he eliminated them from there.13Alternatively, וירץ stems from רוץ [=to run], and the phrase means, “he quickly removed them,” or וירץ stems from רצץ [=to smash], and the phrase means, “and he smashed them,” i.e. after he demolished the altars he further smashed the pieces.—Radak
