Why must he tell Chasidim to love Hashem?
Radak: He says that it is proper that you love Him when you see what He did with me.
Malbim: After speaking against those who speak against Hashem, and it is clarified that there is reward and punishment, and Hashgachah, they should love Him, for He guards Emunin.
Why is there a Segol under the Aleph in "Ehevu"?
Radak: It is because it is followed by Hei, a guttural letter. Normally, in a command, the first letter of the root has a Patach, e.g. "v'Shachatu ha'Pasach" (Shemos 12:21).
What is the meaning of "Emunin Notzer Hashem"?
Rashi: Hashem guards those who believe in His salvation and rely on Him 1 .
Radak: He saved me from every affliction. Emunim is To'ar (kind of person), like "Pasu Emunin" (12:2).
Mesilas Yesharim (Perek 11): Hashem desires only Emunah.
Why does it say "Al Yeser"?
Rashi #1: It is precise Midah k'Neged Midah, like an arrow is [precisely drawn] on the bow string.
Rashi #2: A rope corresponding to a rope, a line corresponding to a line.
Rashi #3: It is an expression of pride, like "Yisrah Asah" (Yeshayah 15:7). He 'pays' (punishes) with pride those who act with pride.
Radak: He 'pays' [those who feel] superior and act with pride.
