Shavua Tov. Tonight and tomorrow is פסח שני. It falls on the fourteenth of Iyar, exactly one month after the date of the preparation of the קרבן פסח.
This special day was mentioned in the Torah when several individuals confronted Moshe Rabbeinu to ask if there was a way to make up their lost ability to offer the Pesach sacrifice, as they were ritually unclean at the time of the sacrifice.
Moshe received an answer from Hashem that the fourteenth of Iyar was the day to offer the sacrifice. In addition to the ritually impure, those who lived far away and didn’t make it to Jerusalem on time, were also given a second chance.
We commemorate this day with no תחנון and some have the custom of eating Matza as well.
May we soon be זוכה to offer the קרבן פסח.
