וְלָקַ֣ח מְלֹֽא־הַ֠מַּחְתָּה גַּֽחֲלֵי־אֵ֞שׁ מֵעַ֤ל הַמִּזְבֵּ֙חַ֙ מִלִּפְנֵ֣י יְהוָ֔ה וּמְלֹ֣א חָפְנָ֔יו קְטֹ֥רֶת סַמִּ֖ים דַּקָּ֑ה וְהֵבִ֖יא מִבֵּ֥ית לַפָּרֹֽכֶת׃
And he shall take a censer full of coals of fire from off the altar before the LORD, and his hands full of sweet incense beaten small, and bring it within the veil.
Mishnah Eduyot
Rabbi Joshua ben. Bathyra testified concerning the blood of carcasses that it was pure. Rabbi Shimon ben Bathyra testified concerning the ashes of purification, that if a defiled person had touched part of them he had defiled the whole of them. Rabbi Akiva added in regard to the fine flour, the incense, the frankincense, and the coals, that if a tevul yom had touched part of them he had made the whole of them unfit.
