Chapter 16

The Passover was to be observed at the place where God chose to have his name dwell, not just anywhere.  Much of the ritual required during this time is reiterated by Moses.  There is this interesting verse:

6 but at the place that the LORD your God will choose, to make his name dwell in it, there you shall offer the Passover sacrifice, in the evening at sunset, at the time you came out of Egypt. [Deu 16:6 ESV]

So they left Egypt at sunset, and they went through the Red Sea in the dark, and the Egyptians died at dawn.  This would be why they couldn't eat any leftovers the next day.  When they left Egypt, they walked all night and into the next day.  They didn't take any leftovers with them.

2021 - Imagine the facilities - the excess lodging - that had to be in Jerusalem in order to observe the Passover properly.

Feast of Weeks.  Seven weeks after grain first harvested.

Feast of Booths at the end of harvest.

Judges to be appointed in the towns, to judge righteously, without favoritism, without corruption.
