Why did he say "Bachanta Libi"?
Rashi: I know that I have a sin, and if the judgment for my punishment comes in front of You, I will not be vindicated - You already tested my heart!
Radak (4): You tested my heart, and know whether my words are Emes.
Malbim: This corresponds to not sinning in thought. You tested my heart, i.e. my thoughts.
What is the meaning of "Pakadta Laylah"?
Rashi: You made a reckoning for the night of the sin of Bas Sheva - "va'Yhi l'Es Erev va'Yakam David
What is "Tzeraftani"?
Rashi: You tested me.
What is the meaning of "Val Timtza"?
Rashi: You did not find Your desire in me.
Radak: Refer to 17:3:2:2.
Malbim: Refer to 17:3:5:4.
Why did he say "Zamosi Bal Ya'avar Pi"?
Rashi: If You will bring up my thoughts to be tested in front of You again, my mouth will not transgress again to say 'test me', like I said "Bechaneni Hashem v'Naseni" (26:2). David had asked Hashem why people say Elokei Avraham, and do not say Elokei David. Hashem said 'I tested him with 10 tests, and he passed all of them', like it says in Shabbos 1 .
Radak: What I thought and said "Bechaneni Hashem v'Naseni" (26:2), if only my mouth did not say it! I was haughty to say so, and I stumbled in it.
Radak: Just like I myself am careful, so I warn others about what I see.
Malbim: You did not find in me an improper thought that my mouth should not say.
I found this in Sanhedrin 107a, but not in Shabbos. Surely David saw through Ru'ach ha'Kodesh that Yisrael will say so [after Anshei Keneses ha'Gedolah will fixed the text of Shemoneh Esre. If he asked about now, did he not know that Hashem does not attach His name to living people?! (PF).
