Jesus knew the Passover dinner would be the last time he met with all His disciples gathered together. The dinner typically involved Seder bread, unleavened to commemorate the Israelites' hasty departure from Egypt; a lamb bone, signifying the Passover lamb that was slain and whose blood marked the threshold of Jewish homes; and bitter herbs, used to prepare the meal (and to remind the Israelites of the bitterness of slavery from which God had rescued them).
