Take a bunch of hyssop, dip it in the blood that is in the basin, and apply some of the blood that is in the basin to the lintel and to the two doorposts. … G-d will pass over the door.
Grass, blood and doorposts? What does this have to do with anything?
Could it be that there is a bigger, hidden message here? After all: grass = plants. Blood = animals. And the doorway = elevated family homes and relationships.
Might this all symbolize something as simple as identifying that the Jewish people are meant to elevate the natural world of plant and animal, bringing them upward to heaven, through our own creative work and loving relationships? And that this somehow makes us worth sparing?
Is this perhaps a lesson we can learn from the days of creation: G-d is not “finished” until mankind has been put in the world? Could this be because we are meant to see ourselves as responsible to complete G-d’s work: elevating nature, through ourselves, upward toward the heavens?
Might this lesson actually be larger than just that one event? After all, the very next verse is:
You shall observe this as a chok [symbolic command] for all time
How? We don’t dip grass in blood and lift it to a doorway now… are we in violation of this commandment?
Or is the mezuzah the way in which we still observe the chok? After all, the mezuzah is made of plant-sourced ink, written on animal-skin parchment, and mounted on our doorposts!
