Beha'alot'cha: Chapter 13
The second Pesach

We hear about the ordinance to keep Pesach at the correct time and about the inner meaning of what happens if it is kept a month later due to uncleanness or traveling.

[Verse 72] We are told that once the Congregation of Yisrael is adorned with her crowns in the month of Nissan she does not remove the crowns from herself for thirty days, so it is still possible to have a second Passover in the second month. The commandments for the slaughter of the Paschal lamb and the delay of the celebration for those who are unclean or far away to the second date are laid out for us. The first Passover is from the right and the second is in the left.
