None of its ashes are brought into the Temple Courtyard for storage, as ibid.:9 states: "And he shall place it outside the camp." The ashes were divided into three portions: one was placed in the chayl one, on the Mount of Olives, and one, was divided among all the priestly guardposts.
The one that was divided among all the priestly watches was used by the priests to sanctify themselves. The one that was placed on the Mount of Olives was used by the entire Jewish people for sprinkling. And the one that was placed in the chayl was prepared and hidden away, as implied by ibid. which states: "It will be a security for the congregation of Israel." This teaches that it was put away for safekeeping.
Indeed, in the chayl, they would put away for safekeeping a portion of the ashes from every red heifer that was burnt. Nine red heifers were offered from the time that they were commanded to fulfill this mitzvah until the time when the Temple was destroyed a second time. The first was brought by Moses our teacher. The second was brought by Ezra. Seven others were offered until the destruction of the Second Temple. And the tenth will be brought by the king Mashiach; may he speedily be revealed. Amen, so may it be G‑d's will.
מאי דהוה הוה
what was, was...
Points to Ponder:
1. Why does the Mishna (and Rambam) tell me about who brought the Para Adumahs in the past? Whatever was, was?
2. What place does a prayer ("may he speedily be revealed...!") have in a book of halacha?
3. What is the difference in context in which the mishna & Rambam quote the list of who brought the para adumahs?

The King Messiah will arise and re-establish the monarchy of David as it was in former times. He will build the Sanctuary and gather in the dispersed of Israel. All the earlier statutes will be restored as they once were. Sacrifices will be offered, the Sabbatical and Jubilee years will be observed, as commanded in the Torah. Anyone who does not believe in him or one who does not anticipate his coming not only denies the Prophets, but also the Torah and Moses our Teacher...
