(in Sommer's translation), "Don't eat it raw or boiled in water; rather, [eat it] roasted in fire." Sommer did not find such a disagreement in this ancient Jewish literature surprising, arguing that two groups in the Biblical period agreed that the Passover sacrifice was important but disagreed on its precise details. The Hebrew Bible frequently notes the Israelites' observance of Passover at turning points in their history. reports God's direction to the Israelites to observe Passover in the wilderness of Sinai on the anniversary of their liberation from Egypt. reports that upon entering the Promised Land, the Israelites kept the Passover on the plains of Jericho and ate unleavened cakes and parched corn, produce of the land, the next day. reports that King Josiah commanded the Israelites to keep the Passover in Jerusalem as part of Josiah's reforms, but also notes that the Israelites had not kept such a Passover from the days of the Biblical judges nor in all the days of the kings of Israel or the kings of Judah, calling into question the observance of even Kings David and Solomon. The more reverent , however, reports that Solomon offered sacrifices on the festivals, including the Feast of Unleavened Bread. And reports King Hezekiah's observance of a second Passover anew, as sufficient numbers of neither the priests nor the people were prepared to do so before then. And reports that the Israelites returned from the Babylonian captivity observed Passover, ate the Passover lamb, and kept the Feast of Unleavened Bread seven days with joy. In early nonrabbinic interpretation The parashah has parallels or is discussed in these early nonrabbinic sources: Exodus chapter 12 The Book of Jubilees taught that the Israelites were forbidden to break any bone of the Passover lamb so that no bone should be crushed of the children of Israel. Philo wrote that God instructed the Israelites to offer unleavened bread and bitter herbs together with the Passover sacrifice because unleavened bread signified great haste and speed, while bitter herbs signified the life of bitterness and struggle that the Israelites endured as slaves. Philo also taught that the deeper meaning was that leavened and fermented foods rose, while unleavened foods remained low, and each of these states symbolized types of the soul. Leavening symbolized the haughty soul swollen with arrogance, while the unleavened symbolized the unchangeable and prudent soul choosing the middle way rather than
