What did Moshe mean when he said to Elazar ha'Kohen "ve'Es ha'Eish Zere 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.
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 - and not exclusively for the Ketores that they were bringing.
Ramban: Perhaps that was because they did so at the behest of Moshe - See Ramban; Otherwise, their sanctification to bring on them a foreign Ketores would have been meaningless.
