Rabbi Aryeh Lebowitz

Aye, the Pasuk says, Yeshua ben Yehud Tzadok ha-Kohen Gadol, so says the Ritva, Yeshua was a Kohen Gadol in the period of Ba'i She'en, and just like we find David ben Yishai,

Melech Yisrael.

Then it says, David ben Yishai, Melech Yisrael.

David was the Melech Yisrael.

Yishai was never the Melech Yisrael.

So you see that sometimes it only goes on the child and not on the father.

That's what the Ritva writes.

Now the problem with that Ritva is, and they point this out in the Mosaddegh Rav Kook Ritvas, they quote an Otzer Balaam ala Ein Yaakov who says, Haplia atzuma, ki lo nim tzezeh b'posok b'kol atanach.

Where exactly does it say, David ben Yishai, Melech Yisrael?

Nowhere in Tanakh or Shas.

So the Ritva says, you know, like we always say, David ben Yishai, Melech Yisrael.

It doesn't say that anywhere, David ben Yishai, Melech Yisrael.

So he suggests that it's a typo in the Ritva, and that really it probably meant to say, Shaul ben Kish, Melech Yisrael, which is the same point, that Shaul was a Melech, Kish was not a Melech, and in Yom HaDav Chaf Bez Amud Bez, that phrase actually appears, maybe on Tanakh.

When in Yom HaChav B'ezon B'ez that phrase actually appears.

And the Ritva over there in Yom HaChav B'ezon B'ez proves from that phrase of Shaul ben Kish, Melech Yisrael, that mikan diktek Rabbeinu Tamzal b'sefer haYasher, which is also problematic because we don't have it in our Sefer HaYasher, she'en lo le'ed l'achton b'shtar, that an eid should not write in a shtar, ploni eid ben ploni, ela ploni ben ploni eid.

The Rabbeinu Talmud learns from here that the word aid at the end, even though it's going on the first name.

So it says the Ritva, it says the Oleg Yom Tov, rather, that if a title at the end could be going on the son, so the title at the end could just as easily be going only on the father, and that's perfectly fine, that it only goes on the father.

In fact, in Evin Ezer, Simim Kuf Chavtes,

But if you only put it at the end, that's kosher as well.

If only the son had a nickname, you would put the nickname next to the son's name before you write the father's name.
