Mishnah Parah 3:10: It would split, [the heifer, due to the flames,] and he [the priest] would stand outside the pit [region designated for the burning], and he would take cedar wood, hyssop and worm silk. He would say to them [to the elders there], "Is this cedar wood? Is this cedar wood? Is this hyssop? Is this hyssop? Is this worm [silk]? Is this worm [silk]?" Three times for each one. And they would say to him, "Yes, and yes," three times for each one.

נִבְקְעָה, וְעָמַד חוּץ מִגִּתָּהּ. נָטַל עֵץ אֶרֶז וְאֵזוֹב וּשְׁנִי תוֹלַעַת. אָמַר לָהֶן, עֵץ אֶרֶז זֶה, עֵץ אֶרֶז זֶה. אֵזוֹב זֶה, אֵזוֹב זֶה. שְׁנִי תוֹלַעַת זֶה, שְׁנִי תוֹלַעַת זֶה. שָׁלשׁ פְּעָמִים עַל כָּל דָּבָר וְדָבָר. וְהֵם אוֹמְרִים לוֹ, הֵין וְהֵין, שָׁלשׁ פְּעָמִים עַל כָּל דָּבָר וְדָבָר:

Mishnah Parah 3:11: He would wrap them [the cedar wood, hyssop and worm silk] with the remainder of the strand [of worm silk] and throw them into her [the heifer's] fire. Once burnt, they would beat it [the remains] with sticks, and sift it with sieves [to produce fine ashes]. Rabbi Yishmael says: with stone slabs and with stone sieves they would do it. Black [charcoal] containing ashes, they would crush it. And [charcoal] not containing [ashes], they would leave [at the pyre]. The bones, either way [whether or not they contained ashes] would be crushed. And they would divide [the ashes] into three portions: one would be placed in the cheil [a low fence and area around the Temple, which served as a boundary, beyond which entry to those impure was prohibited], and one would be placed on the mount of anointing, and one would be distributed among all the priestly rotations.
