What is "Ro'e Yisrael"?
Rashi: Their Leader.
Radak: You led them like a shepherd leading flock.
Malbim: In the past, You tended them and supplied all of their needs.
It already said "Ro'e". Why does it say "Noheg ka'Tzon"?
Malbim: This compares them to a flock among wolves, and they did not fear. "Va'Ynachem la'Vetach v'Lo Fachadu v'Es Oyveihem Kisah ha'Yam" (78:53).
Why does it mention Yosef?
Rashi: All Yisrael are called on his name, for he financed them at the time of famine. 1
Radak: From when the kingdom was split, Malchus Yisrael is called Yosef or Efrayim; [Yosef] was the Bechor in place of Reuven, and Yakov said "v'Yikarei Vahem Shmi" (Bereishis 48:16). I.e. [Am] Yisrael will be called Yosef, just like they are called on my name Yisrael. It says about all of Yisrael "ha'Ven Yakir Li Efrayim", and "Rachel Mevakah Al Baneha 2 " (Yirmeyah 31:19).
Why is Hashem called "Yoshev ha'Keruvim"?
Rashi: This is like it says "v'No'adti Lecha Sham... [mi'Bein Shnei ha'Keruvim]" (Shemos 25:22). Radak - amidst love of them, You dwelled there to meet with them and make Your honor known to them.
Malbim: Refer to 80:2:5:3.
What is the request "Hofi'ah"?
Rashi: Show Your Gevurah.
Radak: Appear to them in Your honor, like of old.
Malbim: Just like You built the Mikdash and dwelled between the staves of the Aron, on the Keruvim, appear now via building the Mikdash!
