What does "Chalalah Zonah" mean?
Above (verse 7), the Torah mentions Zonah, Chalalah, Gerushah. Why did it switch the order here?
Moshav Zekenim (7, citing the Rosh): Regarding a Kohen Hedyot, it began with the most severe - a Zonah` is forbidden due to herself 1 . For a Kohen Gadol, it began with the added Isur, which is most lenient - a widow, who is permitted to a Kohen Hedyot - and teaches in increasing order of severity.
I.e. she sinned. One can be a Chalalah from birth, or through Bi'as Heter (with a Chalal). A divorcee is lightest, for this can occur without any Aveirah at all. (PF)
Why is this not Lav shebi'Chlalos, for which one is not lashed, just like "Al Tochlu Mimenu Na u'Vashel"? Also, it is Nitak l'Aseh ("Ki Im Besulah me'Amav Yikach Ishah")!
Moshav Zekenim: There, the Lav "Al Tochlu" precedes the Pratim. Here, it says "Es Elu Lo Yikach" afterwards - it is as if it says Lo Yikach about each. I cannot elaborate. 1
He did not answer regarding Nitak l'Aseh. It seems that this does not exempt from lashes, since Kidmo Aseh (one can fulfill the Aseh without transgressing the Lav) -Makos 14b. (PF)
Why can the Kohen Gadol marry only a Besulah, but not a widow?
Moshav Zekenim citing R. Yehudah ha'Chasid: The Kohen Gadol says Hashem's name. If he could marry a widow, he might see and desire a woman, and intend when saying the name that her husband die.
Why does it repeat "Ki Im Besulah me'Amav Yikach Ishah"?
