What does Exodus 12:10 mean?
Many practices assigned for this first Passover will become mandatory traditions for the nation of Israel (Exodus 12:14–20). When the Hebrew slaves (Exodus 1:8–14) prepare their Passover lambs (Exodus 12:3–7), nothing is to be left unconsumed. The animal is to be roasted as whole as possible (Exodus 12:8–9). Whatever the family cannot eat—which should be mostly bones—is to be disposed of in the fire. These lambs symbolize the sacrifice of the Messiah, Jesus (John 1:29; 1 Corinthians 5:7). Burning any leftover bits reflects the hasty departure which is to come (Exodus 12:11, 33).The term "Passover" is fairly literal. God will see the blood on Israelite doorways and "pass over" (Exodus 12:12–13) that home as He brings devastation to Egypt (Exodus 11:4–6).
