כלי יקר — וזאת הברכה אשר ברך משה איש האלהים

Q — The Torah's final parsha opens with 'וזאת' — *and* this is the blessing — with a connective vav. Connecting to what?

A — Kli Yakar's elegant answer: this final blessing connects to Moshe's *first* blessing of Bnei Yisrael back at the opening of Devarim — 'ה' אלהי אבותיכם יסף עליכם ככם אלף פעמים.' Chazal record that Yisrael complained: 'משה קיצבה אתה נותן לברכותינו' — you're limiting our blessings to a thousandfold. Moshe replied: 'זו משלי היא, וה' יברך אתכם.' The first blessing was 'משלי' — from Moshe himself. The vav of 'וזאת' attaches the dying Moshe's *second* blessing to the first, but flags the change in source: this one is 'לא משלו... אלא מצד היותו איש האלהים' — not from his personal capacity but as a vehicle of prophecy. The very title of this verse — 'איש האלהים' — is the inflection point. The blessings frame the book of Devarim: one from Moshe the man, one from Moshe the prophet.
