What does this Mizmor discuss?
Malbim: It discusses two ways that Hashem conducts His world. (a) Constant conduct, that He oversees via nature. (b) Miraculous conduct not via an intermediary or Shali'ach, rather, via Himself.
What is "b'Chol Libi"?
Radak: With all my Da'as and Sechel (knowledge and intellect). Thanks is in the heart alone, or with the mouth; song is with the mouth.
What is "Neged Elohim"?
Rashi: In front of the officers.
Radak: In front of the judges and Chachamim. This is like "Ad ha'Elohim Yavo Devar Sheneihem" (Shemos 22:8).
Malbim: Regarding miraculous conduct, it depicts that one who thanks for the good stands in front of Elokim and sees the King Himself, without an intermediary.
