What is the meaning of "Lo Yisechu"?
Rashi: It is an expression of Nesech (a libation). Malbim - they will not bring wine-offerings that accompany Korbanos.
Why does it say "v'Lo Ye'ervu Lo"?
Rashi: Their offering will not be pleasant to Him. Radak ? this is because they transgress His Mitzvos and Toros. Therefore, "Lo Yisechu" (they should not offer).
Malbim: Not only will they not bring wine-offerings ? also the Zevachim are not pleasant to Him; He will not accept them.
How are their Korbanos "k'Lechem Onim"?
Rashi #1: They are like stolen bread, which comes via power and Onim 1 .
Rashi #2: They are like bread of Avelim 2 , which is Tamei (Radak ? because Avelim are Tamei Mes). The coming words support this ? "Kol Ochelav Yitama'u."
Malbim: Zevachim are called Lechem Hashem ? "Ki Es Ishei Hashem Lechem Elokeheim Hem Makrivim v'Hayu Kodesh" (Vayikra 21:6). Their Zevachim are not called so; they are like food that mourners eat ? Seudas Havra'ah (the first meal after burial] is from others. So the Shelamim that they eat are not of Simchah, rather, Seudas Havra'ah.
This is like Ona'ah (overcharging). (PF)
Radak: This is like "Lo Achalti v'Oni Mimenu" (Devarim 26:14) ? in my Aveilus. However, there it is a noun, and here it is an adjective.
What do we learn from "Kol Ochelav Yitama'u"?
Radak: All who eat Lechem Onim are Temei'im (refer to 9:4:3:2). So their Korbanos are Temei'im.
Malbim: An Onen is Metamei his food, for he is Tamei ka'Nefesh. The food of these Korbanos is Metamei those who eat it, for they eat it on their dead Nefesh. They eat this over their own [spiritual] death.
What do we learn from "Ki Lachmam l'Nafsham Lo Yavo Beis Hashem"?
Rashi: This is proper food for them, and "he will not come to Beis Hashem."
Radak: The Korban that they bring for their Nefesh (for Kaparah), it will not come, for they have no benefit from it. It will not atone for them, for they are Mezid. Even when they bring it, they do not repent from their sin!
