Why does it say "Yishlach mi'Shamayim v'Yoshi'eni"?
Radak: Even though they are many, and I am an individual against them, He will send His angels and save me.
Malbim: My haters say so mockingly. They decided that I cannot be saved naturally - I can be saved only if Hashem will send from Shamayim! I.e. I will not be saved.
What is "Cheref Sho'afi"?
Rashi: He saves me from reviling of the one who wants to swallow me.
Radak: The one who wants to swallow me belittles help from Hashem. If Sha'ul did not disgrace Hashem's word, he would not pursue David, for it was already known that Shmuel ha'Navi anointed David to be king.
Why does it say "Selah" in the middle of the verse?
Malbim: This shows that what came before ("Yishlach mi'Shamayim...") is a Ma'amar Musgar (parenthetical comment).
Why did he say that Hashem will send His Chesed and Emes?
Radak: He did Chesed with me initially, to choose me to be king. Now He does Emes to save me from Sha'ul and make me king, for He is Emes and His words are Emes.
Malbim: What they say mockingly, I say truly! I do not hope for natural salvation, rather, for miraculous salvation, whether due to Chesed, or Emes, to fulfill His promise via a Navi that I will reign.
