Why does it say "va'Yitenu Yadam"?
Rashi: They counseled. This is like "Yad Yo'av Itach."
Ibn Ezra #1: This hints to a handshake [to accept] a Shevu'ah. Malbim - if a Kohen married a woman forbidden to him, he vows to divorce her, and then he may serve.
Ibn Ezra #2: Giving the hand shows that he gives himself over to do like the desire and request of the other person.
What do we learn from "va'Ashemim Eil Tzon Al Ashmasam"?
Rashi: This was a Hora'as Sha'ah 1 .
Ibn Ezra: Ashemim is an adjective. The guilty men accepted to offer a ram for a Korban Asham. We do not find this Korban for one who had Bi'ah with a Nochri! Perhaps the heads counseled to do so 2 .
Malbim: They had Bi'ah with a Shifchah Charufah, therefore they were liable to offer Eil Asham (Kerisus 11). Va'Ashemim hints that they admitted. One is liable an Asham only if he completed the Bi'ah (Yevamos 55b). He is believed to contradict witnesses, for he means that he did not complete the Bi'ah 3 .
Malbim: This is unlike Kerisus 11 (refer to 10:19:2:3)! This is like Rashi holds (Gitin 36), that Yovel did not apply in Bayis Sheni, so [after Churban Bayis Rishon] there was no Eved Ivri, and hence no Shifchah Charufah (we hold that she is engaged to an Eved Ivri). The one who says that they had Bi'ah with a Shifchah Charufah holds that she is engaged to an Eved Kena'ani. However, Tosfos (ibid.) holds that Yovel applied in Bayis Sheni, so all agree that Shifchah Charufah applied.
I.e. like the opinion that one may offer Asham Taluy every day. Chachamim forbid to offer any Asham voluntarily (Kerisus 6:3). (PF) `
Presumably, witnesses did not see vividly that he completed the Bi'ah. If so, how is she lashed? We assume that there was full Bi'ah, but indeed, if one of them refutes this, he or she is exempt. When she does not claim so, she is lashed. This is not considered lashes via her admission. (PF)
