147 What are you talking about? So in your opinion the following arent Jewish names?
Names that are Hebrew words that nobody in Tenach had eg: Chaim, Pesach, Yom Tov, Aryeh, Tzvi, Dov, Ilan etc
Names of Tanaim and Amaraim that arent in Tenach: Yochanan, Yanai, Abaye Rava, Huna, Akiva, etc
And of course names that we adoptied from goyim Alexander, Hyrkanus etc
?
Jewish Names are simply names used by Jews if enough Jews name their kid “Lemon Juice” at a certain point it too will become a Jewish name (I don’t know how long it would take) All the more so, if the name is something identifiably Jewish like a yiddish equivalant of an existing Hebrew name then the process is much faster.
