Arba'im Shanah Bamidbar, Avraham Yitzchak Fried (Hebrew, Hardcover)

Arba’im Shana Bamidbar is a one-of-a-kind sefer describing in immense detail (with everything sourced from Chazal, Rishonim, and Acharonim) every aspect of the Jews’ travels through the Midbar, from Yetzias Mitzrayim and onward. It is divided into four sections:
Cheilek Alef: “Lechteich Acharai Bamidbar” — An analysis of various topics, such as the Tzuras HaMachaneh (Jews’ encampment as we traveled through the Midbar), Ananei HaKavod, etc.
Cheilek Beis: “Luach Yemei Ne’urim” — An extraordinary detailed presentation of everything that was done throughout the 40 years in the Midbar, on practically a day-by-day basis (as much as possible based on the sources), with comparative calendars and more
Cheilek Gimmel: “Birurei HaShittos” — An analysis of the various opinions in the Mefarshim regarding when major events occurred
Cheilek Dalet: “Zmanei HaParshiyos” — An encyclopedic (yet concise) treatment of when the events (from Parshas Bo until VeZos HaBerachah) described in the Chumash occurred. Displayed in a user-friendly format; a table which enables readers to look up the specific pasuk they are interested in learning more about.
