What does "Devash (honey)" incorporate?
Why does the Torah forbid bringing Se'or (sourdough) and honey on the Mizbe'ach?
Ramban, Moshav Zekenim (both citing Moreh Nevuchim): Because it was common among the Nochri priests to sacrifice their meal offerings in the form of Chametz and to mix honey in all their sacrifices. 1
Ramban (23:17): Because the former represents Midas ha'Din 2 , and the latter, Midas Rachamim.
Moshav Zekenim: The Kometz may not be Chaser. If there were Chametz or honey, the place of the holes would be missing. Also Lechem ha'Panim (must be Matzah, even though Kemitzah is not taken), lest people say that it is not two Esronim, just it rose because it is Chametz. Anything that requires oil 5 should not be Chametz, lest it raise the dough and people will say that it is not an Isaron. Of Lachmei Todah, 10 loaves are Chametz because they have no oil, and the owner eats them (there is no Kemitzah). Do not ask from Minchas Ma'afe Tanur
Similar to the Matzeivah (an altar made of one stone), which was favored in the time of the Avos, and which Hashem ultimately loathed (See Devarim 16:22), because it became a fixture with regard to idolatry (Ramban).
In fact, the very term Chametz (even though the Torah here uses the word "Se'or" and not 'Chametz'), is a negative term, (like Chometz, in Bamidbar 6:3 and as in Tehilim, 71:4), and, since Korbanos come to bring about an appeasement between Hashem and Yisrael, it is not fitting to bring on the Mizbe'ach something that spoils the natural taste of food, or something that is extreme in its sweetness, such as honey
Having said "Lo Se'aseh Chametz", why does the Torah repeat "ki Chol Se'or ... Lo Saktiru ... "?
Ramban: One prohibits bringing a Minchah that is Chametz, and the other prohibits making the Kometz Chametz and bringing it on the Mizbe'ach.
What does the word "Mimenu" imply?
Ramban: It implies that one may not render Chametz even part of the Kometz.
What do we learn from "Kol Se'or ve'Chol Devash"?
Ramban (citing Menachos, 58a): To teach us that a mixture of Chametz and of honey are also prohibited.
Why does the Torah add "Isheh la'Hashem"?
Ramban: To prohibit whatever is burned on the Mizbe'ach from being brought as Chametz.
Why does the Torah switch to the plural, when it writes "Lo Saktiru", and back to the singular in the following Pasuk?
Ramban, Moshav Zekenim: Because it is referring here to Aharon and his sons, mentioned in the previous Pasuk, whereas the following Pasuk refers to the owner of the Korban.
