Before the tenth plague struck the Egyptians god instructed the Jewish People to slaughter a lamb, a male of the first year, and to sprinkle the blook upon the two side posts and the upper door posts of their houses so that the Angel of Death will pass over the homes of the Jewish People and spare them from the killing of the first born.  The Jewish People were then commanded to roast the lamb with fire and to consume it with unleavened bread and bitter herbs.
