Why did he say "Yafyafisa mi'Bnei Adam"?
Rashi: [Chachamim are] more beautiful than people who engage in temporary life.
Radak: Every doubling (e.g. in Yafyafisa, Yud and Pei are repeated) is to strengthen the matter. The same applies to Yerakrak and Adamdam. I see that your form is nicer than that of other people.
Malbim: Metaphors for physical attributes and praises are taken from nature - "k'Gevo'ah Arazim Gavho v'Chason Hu ka'Alonim" (Amos 2:9), 'Az k'Nemer, Ratz k'Tzvi
What is the meaning of "Hutzak Chen b'Sifsosayich"?
Rashi: Grace is poured onto your lips to rule like the Halachah. "Hutzak" is like "Mutzakos" (Zecharyah 4:2), "v'Yatzak Aleha Shemen" (Vayikra 2:1).
Radak: Also your words [are nicer than other people's; they] are words of Chen, as if grace is poured onto your lips.
Malbim (Derech ha'Muskal): Hashem graced man with ability to speak - Ru'ach Memalela 1 .
This is the Targum of "Nefesh Chayah" (Bereishis 2:7).
What Brachah did he receive?
Rashi: "Hashem Oz l'Amo Yiten" (29:11). The reward is "Hashem Yevarech Es Amo va'Shalom" (ibid.)
Radak: Hashem blessed you forever, for you found grace in the eyes of all. This is truly Hashem's Brachah.
Malbim: His Brachah is l'Olam, unlike physical attributes, which are lost with death of the body.
Malbim (Derech ha'Muskal): He has the ability to acquire eternity, and remain forever.
