Radak: He redeems Yisrael from Galus among the nations. These Parshiyos are for the future.

Malbim: He is prepared to redeem them due to the Kedushah of their deeds.

Radak: He will be sanctified through them via wonders that He will show when He takes them out of Galus.

Sanhedrin 97b: (The verse continues... Melachim Yir'u va'Kamu...") Even though they did not do Teshuvah, they will be redeemed!

Rashi: It is a disgraced Nefesh.

Radak: Kel says, due to Yisrael, which every nation disgraces and despises him, and he is a servant to many rulers - kings will stand for him, and officers will bow to him.

Malbim: They will stand and bow to Yisrael, who now are disgraced in the eyes of the Indian idolaters for three reasons. (a) They think that Yisrael's Nefesh is lowly, from a ruined source. Also refer to 49:7:4:2, 49:7:5:1.

Rashi: One that a Goy despises him.

Malbim: They think that Yisrael's bodies are lowly, and do not want to touch them.

Malbim: They think that Yisrael are at a low level due to acquisition. They are unlike a slave who has one master, rather, a slave of many masters. He is forced to serve all of them, harsh labor.

Rashi: They will see him, and stand.

Rashi: He is faithful to guard His promise to Avraham, like it says "v'Hine ha'Shemesh va'Alatah Hayah v'Hine Sanur Ashan..." (Bereishis 15:17).

Radak: For the sake of Hashem, who helps Yisrael, they will do this, like Zecharyah said (8:23) "Yachaziku Asarah Anashim [mi'Kol Leshonos ha'Goyim v'Hecheziku bi'Chnaf Ish Yehudi Leimor] Nelechah Imachem Ki Shamanu Elokim Imachem." He is faithful in the promise that He made to Yisrael, and for the sake of "Kedosh Yisrael", that He chose you.

Malbim: He is faithful for two reasons. (a) He is faithful to fulfill His promise. (b) Refer to 49:7:8:2. The Ge'ulah will come before its [latest possible] time, if they improve their deeds, and if not, it will come in its time.

Rashi: He is Kedosh Yisrael, and He chose you.

Malbim: He is faithful due to the Kedushah of their deeds. He chose them due to their virtue - "Kedosh Yisrael v'Yivcharecha"!
