Final answer:
The two main things eaten by the Hebrew families during Passover are lamb and unleavened bread, which are steeped in symbolic meaning related to the Exodus story.
Step-by-step explanation:
During the Jewish holiday of Passover, the two main things that were eaten by the Hebrew families are (a) Lamb and unleavened bread. This tradition comes from the story of Passover recounted in the book of Exodus, where the Israelites are instructed by Moses, as commanded by God, to slaughter a lamb and mark their doorposts with its blood to protect their firstborn from the final plague. They were also to eat this lamb with unleavened bread and bitter herbs, signifying the haste in which they left Egypt, as there was no time for the bread to rise. Unleavened bread or matzoh is a crucial symbol during Passover, as it represents the speed of their departure from slavery and signifies humility and freedom from the 'puffed up' nature of leavened bread.
