וַיָּקֻ֕מוּ וַיָּסִ֙ירוּ֙ אֶת־הַֽמִּזְבְּח֔וֹת אֲשֶׁ֖ר בִּירוּשָׁלִָ֑ם וְאֵ֤ת כָּל־הַֽמְקַטְּרוֹת֙ הֵסִ֔ירוּ וַיַּשְׁלִ֖יכוּ לְנַ֥חַל קִדְרֽוֹן׃
And they arose and took away the altars that were in Jerusalem, and all the altars for incense took they away, and cast them into the brook Kidron.
Rashi on II Chronicles
the altars for incense a place where there were priests and Levites.
