Deuteronomy 9:21 Halakhah

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 your sin, the calf which ye had made, and burnt it with fire, and beat it in pieces, grinding it very small, until it was as fine as dust; and I cast the dust thereof into the brook that descended out of the mount.—
