Out of Egypt... the Paschal Lamb... appointments in time... leaven and matzah... the Song at the Sea... a Messianic prophecy... a synopsis of the Passover Torah readings...
Passover is the springtime holiday when Jews celebrate how G-d “passed over” the homes of our ancestors before taking them out of Egyptian slavery.
Passover is celebrated by ridding our homes from chametz (grain that has risen) eating special foods (matzah and bitter herbs), retelling the story of Exodus, and desisting from work.
