What is the beginning of the Pasuk coming to teach us?
Rashi: It teaches us that a man who lies on the Mishkav or Moshav of a Nidah 1 is Tamei and requires Kibus Begadim, as stated in the previous Pasuk.
Rashi: Even though he did not touch her.
What sort of K'li is the Pasuk referring to?
Rashi and Rashbam: It is referring to Merkav, 1 since the Torah writes "be'Nog'o bo" and, as opposed to Mishkav and Merkav, which are Metamei via Masa as well as via Maga, Merkav is only Metamei via Maga and does not require Kibus Begadim.
The Dinim of Mishkav, Moshav and Merkav regarding a Nidah and a Zavah are equivalent to those of a Zav (Rashi), as presented above, Pesukim 4-10.
If the Pasuk is talking about Merkav, why does the Torah write "asher Hi Yosheves alav", and not 'Rocheves alav'?
Pesachim, 3a: Even though the Torah mentions "Merkav" with regard to a man
Which is why women tend to ride side-saddle.
What are the implications of the phrase "Asher Hi Yosheves alav"?
Nidah, 54b: It implies "Hi", 've'Lo Damah'
