Question: Where can I find the Hebrew text of
מדרש ילמדנו (מאן) ילקוט תלמוד תורה - פרשת בהעלתך
Midrash Yelamdeinu, Yalkut Talmud Torah, Parshat Beha'alotecha
The citation I have states that it was published as the "Mann edtition", in Cincinnati, 1940. No other details are provided.
Answer: This midrash was published in volume 2 of The Bible As Read and Preached in the Old Synagogue, by Jacob Mann. Although this book appears to be in English, both volumes include extensive Hebrew sections with the texts of midrashim. Volume 1 was published in 1940; Volume 2, published in 1966, includes this midrash on Bamidbar, Parshat Beha'alotecha. This chapter is entitled:
ילקוט תלמוד תורה לבמדבר ודברים
At JTS, this book is in the Reference and Main collections at BM 660 M3.
