Le Deutéronome 33:1 Commentaire : Rashi, Chizkuni, Da'at Zekenim & Ramban

וזאת הברכה … לפני מותו AND THIS IS THE BLESSING [WHEREWITH MOSES … BLESSED THE CHILDREN OF ISRAEL] BEFORE HIS DEATH — i.e., quite near to his death. “For” said he, “if not now, when?” (Sifrei Devarim 342:7).

וזאת הברכה, “and this was the blessing, etc.” the letter ו at the beginning of the word וזאת, indicates that the paragraph following is a continuation of what we have read immediately before. Whereas up to now Moses had admonished the people, he now switched to blessing them.

וזאת הברכה אשר ברך משה וגו, “and this is the blessing which Moses bestowed, etc.;” Rabbi Joseph Kara wrote that the reason that Moses added as his title the words: איש האלוקים, “the man of G–d,” was to tell the people that G–d had instructed him to pronounce these blessings.
