This Torah portion tells the story of Korach.
Korach was a very wealthy and intelligent Yehudi that had everything one can ask for. He was an important leader of Israel, but let himself be manipulated and influenced by Dasan and Aviram (two bad characters).
Unfortunately jealousy got the best of Korach. Korach together with 250 tribal judges, rebelled and contested the authority of Moshe and Aharon, accusing them of abusing their power, creating a dictatorship and only showing prefiencial statuses towards the Cohanim.
Moshe tried to talk with them and said, "Take the necessary elements to present before G-D "Ketoret" (Holy Incense), and like this we will ultimately see who is the man that G-D has chosen as His Messenger ...
And so it happened each one took the holy incense and presented it at the entrance of the Mishkan in front of Moshe and Aharon.
The floor began to shake until the ground opened its mouth and swallowed Korach, Dasan and Aviram together with their families and all of their belongings.
The ground above them then closed and they disappeared from the surface.
Then G-D sent a blazing lightning that consumed the 250 judges involved in the incense.
The People of Israel, upset by the misfortunate occurrence that had just happened, decided to face off against Aaron and Moses.
G-D's let out his anger against the people causing a plague with a death toll of 14,700 victims!
Seeing this Aharon hurried and offered a Ketoret offering to G-D and that's how the plague stopped.
Then G-D ordered Moshe to seek a wood rod (Scepter) from the representatives of each tribe. On each rod to write the name of the representative, and on the staff of Levi write the name of Aaron. Then to be placed inside of the Ohel moed.
The next day the staff that has flowers on it will be the person chosen by G-D.
This was done, and the very next day the rod of Aaron had blossomed. Moshe showed the People. G-D Ordered him to keep this staff in memory of the rebellion ... in order that no additional deaths occur.
The Perasha ends mentioning the important responsibility of the Kohanim and Leviím to guard the sanctity of the Mishkan, and the obligation of the Jewish people to tithe 10 percent of their income to the Leviim and the Kohanim for being G-D's servants.
Shabbat Shalom !!
