Tell the whole community of Israel that on the tenth day of this month each man is to take a lamb for his family, one for each household… Take care of them until the fourteenth day of the month, when all the people of the community of Israel must slaughter them at twilight. Then they are to take some of the blood and put it on the sides and tops of the doorframes of the houses where they eat the lambs… The blood will be a sign for you on the houses where you are; and when I see the blood, I will pass over you. No destructive plague will touch you when I strike Egypt. – Exodus 12:3-4, 6-7, 12
What was the significance of putting blood on the doorposts? One very important thing to realize is how it foreshadows the future shedding of blood of Christ, that protects us from judgment, just as the blood here protected the families from judgment.
But yet, the act of putting blood on the doorposts says other things as well. One is that it was a public commitment to the God of Israel in that hostile land, in which that kind of sacrifice was an abomination, which would lead to the person’s being stoned (Ex. 8:26). Only those that were convinced that God would triumph over the Egyptian gods would have done so because of fear of public execution.
Also, putting the blood on the doorposts was a mark of faith that apparently was not limited to Israelites, but anyone who placed his or her faith in God. The text says that many others left Egypt with the Israelites (Ex. 12:38) – perhaps they too had claimed this God by marking their homes. Even some of Pharaoh’s officials feared the Lord – could some of them have even done it? Interestingly, entire homes and families were saved, just as in the New Testament, entire families were baptized and saved (Acts 16:34). Even Rahab the harlot was able to save her family by marking her home with a scarlet cord! (Josh. 6:25) The Bible often talks about salvation in terms of families, while we think in terms of individuals.
Finally, it is amazing that God told people to make a sacrifice and put the blood on their homes. Normally sacrifices were made at an altar in a tabernacle or temple, and only the ceremonially clean could enter in. God’s great shekinah glory would be very present at the altar, apart from the rest of the people. Here, God was telling them to anoint their home as God’s altar and publically place their faith in him. God’s presence came that night and to those who did not fear him, it lead to judgment. But to those who had faith, it would set them free.
