What is "bi'Chnafayich"?
Radak: In the corners of your garment 1 . This is like "va'Yiz Nitzcham Al Begadai v'Chol Malbushai Eg'alti" (Yeshayah 63:3).
Radak citing Targum Yonasan: [Even] covertly [it is found that you spilled innocent blood]. This is like "v'Lo Yegaleh Es Kenaf Aviv" (Devarim 23:1), something hidden of your father, i.e. his wife.
Abarvenel: For honor and glory. They prided themselves for this!
"Nimtze'u" is plural, and "Dam" is singular!
Radak: It is as if it says Damim, for it says "Dam Nefashos."
Who did they kill?
Malbim: They killed the Nevi'im who came to rebuke them, for they thought that the Nevi'im come to veer them from the good path.
What is the meaning of "Lo va'Machteres Metzasim"?
Rashi: The poor that you killed - you did not find 1 them tunneling into the house. Radak - "if the thief is found in [such] a tunnel, and he struck and killed him, there is no blood (liability for him)" (Shemos 22:1). You did not find them there. Why did you kill them? They are innocent!
Malbim: These people thought that they are on a good path, and the Nevi'im telling them to change are like thieves trying to steal their good path from them, therefore they killed them. You did not find them in a tunnel coming to steal money! Your sin is three-fold. (a) You remained on your bad path, and added to it. (b) You killed the Nevi'im, as if they came to make you stray from the good path. (c) You say that you did not sin (Beis Shamai 35).
Rashi: Metzasim is past tense speaking to a female (with a pronoun at the end - Radak). This occurs often in Yechezkel, e.g. "At Nesatim" (16:58).
What is "Ki Al Kol Eleh"?
Rashi: They were rebuking you with these words.
Radak: This is connected to the coming verse (you claim innocence from all this).
Abarvenel: Since they were not found in a tunnel, why did you kill them?! I rebuke you for all of this.
