In the context of Passover, chematz (leaven) symbolizes the arrogance and puffiness of Pharaoh and the Egyptians. According to biblical narrative, during the Exodus from Egypt, the Israelites were commanded by God to refrain from consuming chematz during the seven days of Passover. This prohibition served as a reminder of their hasty departure from Egypt, when there was no time for the bread to rise, and of the need to reject the oppressive nature of the Egyptian regime.

Symbolically, leaven, which causes bread to rise and puff up, is associated with pride, hubris, and self-exaltation. The removal of leaven from homes and the consumption of matzah (unleavened bread) during Passover represent the casting off of these negative attributes and promoting humility and a connection to the divine. Therefore, chematz symbolizes the negative aspects of human behaviour that contribute to the enslavement of the self and others.
