Korach – It is never too late
Korach was a cousin of Moses. He challenges Moses authority and the very divinity of the Torah.
His underlying agenda is one of burning jealousy and resentment. He wants a higher position himself.
As with many great politicians he dresses up his arguments in a way that makes them acceptable even convincing to the masses
“You take too much upon yourselves, for the entire congregation are all holy, and the Lord is in their midst. So why do you raise yourselves above the Lord’s assembly?”
Everyone is holy translates into modern terminology today as “everyone is equal”
Korach is both right and wrong. Essentially all human beings are created in the image of God and from that perspective equal. However, there is a concept of equal but different. We all have a specific role and mission in life and Moshe was chosen to lead the people as was Aharon.
The positive lesson we learn from Korach is to look at people as essentially holy , not to judge people. Yet at the same time we must not covet other people’s possessions or positions. Rather we must acknowledge that each person has a unique role to play. Hashem wants us to be the best we can be and He provides for us the exact environment to facilitate that.

To conclude with a fascinating passage of the Talmud that relates that in Psalms we mention about the Bn’ei Korach. They were Korach’s sons who according to our Parsha were swallowed up like Korach. However, the Talmud fills us in and explains that they are mentioned in Tehilim since they prayed at the last moment and did teshuva and managed to climb out of being entirely swallowed up by the depths of the earth. These tehilim express their prayers. (Talmud Sanhedrin 110a )
Judaism teaches us that it is never too late to make changes in our life. This is a wonderfully upbeat message and testament to the power of free will that God has gifted to humanity.
Shabbat Shalom
