Pesach (Passover) begins tomorrow. The 8 day celebration (festival) commemorates the emancipation of the Israelites from slavery in ancient Egypt.
During this time I do not eat leaven bread.
The Israelites left in such a hurry that their bread didn’t have time to rise. So to commemorate you eat unleaven bread.
And there are Seders 🙂 Hey if you have a Jewish friend ask if they are having a Seder and see if you can go.
