The Rebbe says:
1. In this week’s Torah portion Moshe Rabbeinu (Moses our teacher) and Aharon Hakohen (Aaron the High Priest) plead with Hashem not to destroy Korach’s entire congregation; rather, Hashem should just destroy Korach because he was the one who incited and convinced everyone to rebel against Moshe Rabbeinu.
The Torah says, “Hashem spoke to Moshe and Aharon, saying: ‘Separate yourselves from among this congregation and I will annihilate them in an instant’. They (Moshe and Aharon) fell upon their faces and they said, ‘Almighty, the G-d of the spirits of all flesh; if one man sins shall You be angry with the entire congregation?’”
Rashi comments on this verse and explains why Moshe and Aharon prefaced the words, “Almighty, the G-d of the spirits of all flesh”, before their actual argument of, “if one man sins shall you be angry with the entire congregation?”. Rashi explains that Moshe and Aharon were saying, “(Hashem You are the) Knower of thoughts. Your attributes are not like mortal attributes. A mortal king against whom some of his kingdom acted insolently does not know who the sinner is and therefore when he is angry he punishes them all. But You- to You all thoughts are revealed and you know who the sinner is. Therefore, “if one man will sin will You be angry with the entire congregation?”
