Passover, Pesach in Hebrew, (April 16-23, 2022) commemorates the Exodus from Egypt. After generations of bondage, God sent Moses to demand that Pharaoh release the Jewish people from slavery. When he refused, God afflicted the Egyptians with Ten Plagues. Days after Israel's departure, Pharaoh and his army pursued them, only to be drowned, as the Sea of Reeds split for Israel and reconverged upon the Egyptians.
On Passover we eat matzah – both the food we ate as slaves and the symbol of our redemption. We may neither eat nor own any foods containing leaven. We prepare for Passover by cleaning the house, searching for and removing all item containing leaven and burning the remainder on Passover eve.
