Bearing in mind the Mitzvah "Ki Im Besulah me'Amav Yikach Ishah" (in Pasuk 14), what is this Pasuk coming to teach us?
What is the word "ve'Hu" coming to include?
Horayos, 12b: The 'Hey' incorporates a Kohen Gadol who is serving and one who stood down, eiher because of Tum'ah or on account of a blemish. 1
Horayos, 12b: The 'Hey' incorpotates a Mashu'ach Milchamah in the obligation to marry a Besulah. 2
Yerushalmi Horayos, 3:2: The "Hu" comes to preclude a king and a Nazir from the obligation to marry a Besulah. 3
Why does the Torah insert the word "Ishah"?
Yevamos, 59a: In order to Darshen "Ishah" - 'Achas, ve Lo Shetayim', forbidding the Kohen Gadol to have two wives.
What are the implications of "Yikach"?
Yevamos, 59a: It implies marriage - not Erusin. Consequently, if the Kohen Gadol berothes a Besulah and she becoms a Bogeres, he is not allowed to marry her. 1
See Torah Temimah, note 81.
Why does the Torah write "bi'Vesulehah"?
Targum Yonasan and Yevamos 59a #1 (according to R. Meir): "Besulehah" implies that she has all her Besulim, to preclude a Bogeres, whose Besulim have (partially) 1 fallen out; Whereas "bi'Vesulehah" teaches us that the prohibition is confined to the location of the Besulim - precluding Bi'ah she'Lo ke'Darkah (unnatural relations) which will not disqualify her.
Yevamos 59a #2 (according to R. Eliezer and R. Shimon): "Besulehah" implies even some Besulim - a Bogeres; whereas Bi'Vesulehah teaches us that she must be a total virgin - that she did not have relations wih a man even she'Lo ke'Darkah
