Deut 9:21

וְֽאֶת־חַטַּאתְכֶ֞ם אֲשֶׁר־עֲשִׂיתֶ֣ם אֶת־הָעֵ֗גֶל לָקַחְתִּי֮ וָאֶשְׂרֹ֣ף אֹת֣וֹ בָּאֵשׁ֒ וָאֶכֹּ֨ת אֹת֤וֹ טָחוֹן֙ הֵיטֵ֔ב עַ֥ד אֲשֶׁר־דַּ֖ק לְעָפָ֑ר וָֽאַשְׁלִךְ֙ אֶת־עֲפָר֔וֹ אֶל־הַנַּ֖חַל הַיֹּרֵ֥ד מִן־הָהָֽר׃

And I took that sinful thing, the calf you had made, and burned it in the fire. Then I crushed it and ground it to powder as fine as dust, and I cast it into the stream that came down from the mountain.
