Maseches Bechoros Daf 4 and 5a

So the Gemara says just about a little bit more than halfway down, I should say.

According to you, Abaye, that we know that the seh of the levim was the cause for the change in the behema of the Yisrael, because that's what the Torah says.

So the levi was able to give a seh, and that would then take over the halachic status of the b'chor, of the Yisrael.

L'didach the amres behemtom.

It would then only make sense that a Levi who has a seh to offset the chamor of Yisrael, only if the Levi has a seh should he be exempt from Petr chamor.

Then perhaps, again, if you're being very granular about it, if you're saying that the reason that we know that...

The reason that we know that a Levi's putter from Petr Hamor is because his seh offset the Hamor of Yisrael.

Well, then it's only true if he has a seh.

But what if a Levi doesn't have a seh? Then that Levi would be chayim.

And says Rav Safra, I'm not only punching Abai, I have a question on both of you, both Abai and Rabba.

If a Levi is already 30 days old, then he should be Pater from Petr Hamor.

Because once you hit 30 days, that's census.

That's when they are willing to count you as a Levi.

You're not even a Bar Kayyam at that point.

If you're less than one month old and a Levi, then that means you should be Chayiv if there is a B'chor.

then lo-livka, then you shouldn't be pater.

So, says the Gemara, not only that, let me ask you yet another question.

We know that the male levies were going to be exempt, levia, lo-tivka, but perhaps a levia, which is a female Levite, maybe she should, in fact, not be exempt.

Maybe she'd be obligated if she had her own animal.

So, but if that were to be true, then why did Rav Adabar Ava teach us that we see that a leviah does have an application to the general world of levying, in that she is exempt, was the exact case of my family, where my wife is a baslevi.

There we see, like this, that Rav Adabar Ava says, So, asking this whole slew of questions, the Gemara says that that particular one is really not a good one.

It's just a comment about Petarechem, and it's not a question of the gender of the parent.

Just we want to know about the animal.

Was the animal Petarechem, yes or no? Fine.

So then, therefore, even Olivia would be exempt.
