What is the meaning of "Ein Imcha Lazor?"?
'Rashi': Even though we are few and they are like sand of the sea, and [naturally] we cannot stand against them, You can save many or few.
Gra: According to nature, the stronger should win, and all the more so the more numerous. For You, there is no difference [whom You cause to win].
Malbim: People have limited power, so it is easier for them to help the side that has many, for also that side contributes. It is hard to help one who has no strength, for then the helper must do everything. You have unlimited ability; You do not need help. No one joins to help You, to make a difference which side You help, whether they have many, or no strength, and rely on You alone.
He already said "Alecha Nish'anu." Is "uv'Shimcha Vanu" another reason to help us?
Gra #1: No. We rely on You because You are called Elokei Yisrael.
Gra #2: Yes. We constantly mention Your name.
Malbim: Yes. You must show wonders for us to aggrandize and sanctify Your name
What is the meaning of "Al Yatzor Imcha Enosh"?
'Rashi': Our enemies should not have a man to rule over Your nation, lest they say that their gods defeated us.
'Rashi' citing the Rav: We should not be held back from vanquishing our enemies. "Atzar" is holding back, like "v'Atzar Es ha'Shamayim" (Devarim 11:17), "Ki Atzar Atzor" (Bereishis 20:18), "Im Tatzereni" (Shoftim 13:16).
Radak #1: No one of them should be king together with You. This is like "Yoresh Etzer" (Shoftim 18:7).
Radak #2: No strength should remain in them.
Malbim: The victory should be in a way that shows that man did not overcome the enemy, only Hashem did.
