He died again

Daf Hashavua

Bava Basra 15a

The Gemoro asks  who wrote the last eight Pesukim in the Torah (וימת שם משה) and  answers two Tirutzim.

The Zohar*  has a third answer. 

"Moshe was Niftar and Hashem brought him back to life. Moshe wrote then the last eight Pesukim, and died again."

The Malbim has a beautiful  pshat on the Pasuk 

“תורת ה' תמימה    ”-The Torah is complete  – “משיבת נפש”- because Hashem brought back the  Nefesh of Moshe to write and complete the last eight 

Pesukim in the Torah.

*With this Zohar we might be able to answer  Tosfos (Menachos 30a)  Kushya.

"How could Moshe have died Shabbos at Mincha time when that year the 7th

of Adar was on a Friday."

It is possible that Moshe died on Friday the 7th of Adar. He was brought back 

to life and wrote the 13 Sifrei Toras on Friday. He died again on Shabbos the 

8th of Adar.(אמבצי)
