In the first two verses we read there is more emphasis on the door and the blood than there is on the house. But the result involved God passing over the entire house. The door in the context of the story represents the entire house. The idea is that if the death angel could not get passed the door, the death angel could not get into the house.
In this case, the blood of the lamb was not caught in a basin but drained from the lamb's throat directly on the threshold of the door. Then, it was splashed on the doorposts and on the lintel. There is reason to believe this may be true because the Hebrew word for "threshold" is the same as for the word "basin."
The similarity is so striking that when the Jews involved Greek scholars to translate the Bible into Greek, called today the Septuagint, that version translates that word into "threshold" rather than "basin."
If this is true, and it seems there is a strong chance of it being true, then in order to go through the door, the death angel would have been surrounded by blood. It was on the threshold, on both doorposts, and on the lintel as well.
Now, there was something mentioned here we just kind of passed over and that was in verse 22. At this point, it is an abstract idea or concept, something we are going to think about and that is, "none of you shall go out of the door of his house until morning." Why were they not allowed to go out and why, when they were allowed to go out, did it have to be morning?
What's he talking about? What time is he talking about? What event is he talking about? He is talking about the Passover. He is talking about what one does with the blood right after the lamb is killed.
One cannot go out of Egypt by night and stay in his home at one and the same time. You can't "leave" and "stay" at the same time. You can't sit in your house until morning and walk out of Egypt at the same time. You can't do both! The events of Passover and the events of The Night To Be Much Observed (the first day of Unleavened Bread) occurred on two different nights.
This is an instruction specifically for those people in Egypt. Moses gave them instruction right on the spot there in Egypt. They were not to go out of their houses until morning—until the break of day. When the Death Angel passed through, they were in their houses. They were not in the city of Rameses. I will tell you why in just a little bit. Again, the movie shows this reasonably well. They were in their homes when the Death Angel passed through.
Do you see what that says? After killing the lamb, dashing its blood upon the doorposts and then roasting the lamb, the Israelites were specifically warned to remain in their houses until morning. This sets up a physical impossibility for the 15th Passover folks. One cannot remain in one's house on the 14th and flee Egypt on exactly the same day.
We of course have read these scriptures a number of times. They are a clear message of what our responsibility is once we have been placed within the household of God: We are to stay within it in service to the Body.
