What is "Atzeres Bogedim"?
Rashi: It is gatherings of traitors.
Radak, Targum Yonasan: They gather to speak treachery and Sheker.

Malbim: They gather in front of Hashem to serve and pray, but it is treachery, for their heart is full of sin - "Lo Uchal Aven va'Atzarah" (Yeshayah 1:13).
Malbim (2): This is like "ba'Shem Bagadu Vanim Zarim 1 " (Hoshe'a 5:7).
Malbim (2): There are two reasons why people have children. (a) To perpetuate the species - also animals do so. (b) Man's Nefesh speaks; his children are his heirs for this. The nation had Banim Zarim because they transgressed two Brisim regarding these - Bris Basar ("Kulam Mena'afim") and Bris ha'Lashon ("va'Yadrechu Es Leshonam" - verse 2).
