(Mishnah): If an ox gored and killed a man, if it was Mu'ad, it pays Kofer. If it was Tam, it is exempt;

In either case, the ox is killed.

The same applies to killing a boy or girl.

If it killed a slave, it pays 30 Shekalim, even if the slave is worth much more or much less.

(Gemara - Beraisa #1 - R. Eliezer): "The owner of the ox is clean'' from paying half-Kofer;

Objection (R. Akiva): (A Tam only pays from itself.) We must stone it immediately. (Obviously it does not pay Kofer!)

Answer (R. Eliezer): I discuss only when it intended to kill an animal, and it killed a person... (or other cases in which it is not stoned).

Question: Rather than challenging R. Eliezer, [R. Akiva] should challenge himself! (Below, he expounds that a Tam is exempt from paying Demei Eved, i.e. 30 Shekalim for an Eved Kena'ani.)

Answer #1 (R. Maisha): The case is, he slaughtered it [before the final verdict. This could also answer for R. Eliezer! The Bavli says that R. Akiva hoped to hear another answer from R. Eliezer - MAHARA FULDA.]

Answer #2: Some want to say that after he learned from R. Eliezer, [R. Akiva] further said (expounded that a Tam is exempt from Demei Eved). I said only when it intended to kill an animal, and it killed a person, or [it intended to kill] a Nochri, and it killed a Yisrael, or [it intended to kill] a stillborn baby, and it killed a viable baby, so is exempt [from Misah].

Question: How does R. Akiva expound "u'Va'al ha'Shor Naki''?

Answer: He is clean (exempt) from Demei Eved.

Question: Does R. Akiva not hold that [a Tam] is exempt from half-Kofer? (The verse from which R. Eliezer exempts from half-Kofer, R. Akiva uses for Demei Eved!)

Answer: "Im Kofer Yushas Alav'' discusses a Mu'ad. (There is no source to obligate a Tam.)

Question: Does R. Eliezer not hold that [a Tam] is exempt from Demei Eved? (The verse from which R. Akiva exempts from Demei Eved, R. Eliezer uses for Kofer!)

Answer: It says here [regarding a slave] "ha'Shor Yisakel'', and it says there [regarding Kofer] "ha'Shor Yisakel.'' Just like there ha'Shor Yisakel discusses a Mu'ad, also here ha'Shor Yisakel discusses a Mu'ad.

Question: Does it not say "Sakol Yisakel ha'Shor'' [about a Tam? We should learn from there!]

Answer: It is better to learn ha'Shor Yisakel from ha'Shor Yisakel, and not to learn ha'Shor Yisakel from Sakol Yisakel ha'Shor.
