What did Moshe mean when he said to Elazar ha'Kohen "ve'es ha'Eish Z'rei Hal'ah".
Rashi #1 and Targum Yonasan: He was instructing him to scatter the burning ashes of the Ketores from the pans on to the ground.
Seforno: Not by the location where they poured the ashes from the Mizbe'ach, since they were from a Ketores Zarah.
And what did he mean when he said "Ki Kadeishu"?
Rashi: He meant that the men had made them into K'lei Shareis, 1 thereby rendering them Asur be'Hana'ah.
Ramban: Hashem declared them Hekdesh so that they should be a sign for Yisrael.
Seforno: They had sanctified them for general use
Ramban perhaps that was because they did so at the behest of Moshe (See Ramban); Otherwise, their sanctification to bring on them a foreign Zarah would have been worthless.
