What does Exodus 12:9 mean?
Israel is about to leave Egypt in a great rush (Exodus 12:29–33). The people are to eat this meal prepared for travel (Exodus 12:11). Keeping the head, legs, and entrails with the lamb during cooking would have been unusual, but also much quicker than fully butchering it. Most scholars assume that parts such as the intestines would have been removed, since leaving feces in the meat would contaminate the entire meal. Other organs, such as lungs, liver, and heart were to be kept. The limbs were not to be removed; the animal was to be roasted as "whole" as possible.Roasting was the only proper way to prepare the designated sacrificial lambs (Exodus 12:5–6) for eating. This verse emphasizes that the cooking method mattered. The lambs are symbolic of the death of the Messiah; a role which would later be fulfilled through Jesus Christ (John 1:29; 1 Corinthians 5:7). Every bit of the lamb was to be consumed (Exodus 12:10), and boiling would disperse some of the flesh into the water.
