The importance of Passover, particularly the act of eating, is central to God's purpose as it signifies a lifelong commitment beyond mere belief in the sacrifice of Jesus Christ. In John 6:54-58, it is emphasized that whoever eats His flesh and drinks His blood has eternal life, and He will raise them up on the last day, highlighting that eating this bread ensures eternal life. Exodus 12:11-13 instructs the Israelites to eat the Passover in haste, with specific preparations, as the Lord will pass over their houses marked with blood to spare them from the plague in Egypt. Further, Exodus 12:8-9 details that the flesh must be eaten on that night, roasted in fire, with unleavened bread and bitter herbs, adhering to precise instructions. Exodus 12:44 and 12:46 specify that only circumcised individuals may eat it, and it must be consumed within one house without carrying any flesh outside or breaking bones. Numbers 9:1-3 and 9:9-12 reinforce that the Passover must be kept at its appointed time on the fourteenth day of the month at twilight, according to all its rites and ceremonies, including eating with unleavened bread and bitter herbs, even for the second Passover a month later if one was unable to participate initially. God's command is clear that to keep the Passover, one must eat of it on the night of the fourteenth, underscoring the critical nature of this act in obedience to His instructions.
