Never heard of Reb Levy YItzchak Barditchever zt"l

 

The פיוט of the first day of Shachris Rosh Hashana (אבן חוג) it says :  "סלוף דינה ביהוסף להנחות" The Chasam Sofer quotes from the ספר טיב גטין who the Chasam Sofer  quotes from a מקובל, who said, that when יוסף was in לאה's womb his name was יהוסף and when דינה was in רחל's womb her name was דין. After the mothers were switched, יהוסף lost the ה and became יוסף and דין received that ה and became דינה ---- Actually, the טיב גטין doesn't quote this from an unknown מקובל but quotes this from his Mechuten  הרב לוי יצחק מברדיטשוב זצ. In all probability, the Chasam Sofer never heard of the קדושת לוי and therefore refers to him as  an unknown מקובל אחד. R. Levi Yitzchok Barditchev - & The Chasam Sofer  were both Niftar on כ"ה תשרי
