The Passover ritual, as appointed here, divides itself into two main parts--the sprinkling of the sacrificial blood on the door-posts and lintels, and the feast on the sacrifice. These can best be dealt with separately. They were separated in the later form of the ritual; for, when there was a central sanctuary, the lambs were slain there, and the blood sprinkled, as in other expiatory sacrifices, on the altar, while the domestic feast remained unaltered. The former was more especially meant to preserve the Israelites from the destruction of their first-born; the latter as a permanent memorial of their deliverance. But both have perpetual fitness as prophetic of varying aspects of the Christian redemption. I. The ritual of the protecting blood. In the hurry and agitation of that eventful day, it must have seemed strange to the excited people that they should be called upon to observe such a service. But its institution at that crisis is in accordance with the whole tone of the story of the Exodus, in which man is nothing and God all. Surely, never was national deliverance effected so absolutely without effort or blow struck. If we try to realise the state of mind of the Israelites on that night, we shall feel how significant of the true nature of their deliverance this summons to an act of worship, in the midst of their hurry, must have been. The domestic character of the rite is its first marked feature. Of course, there were neither temple nor priests then; but that does not wholly account for the provision that every household, unless too few in number to consume a whole lamb, should have its own sacrifice, slain by its head. The first purpose of the rite, to provide for the safety of each house by the sprinkled blood, partly explains it; but the deepest reason is, no doubt, the witness which was thereby borne to the universal priesthood of the nation. The patriarchal order made each man the priest of his house. This rite, which lay at the foundation of Israel's nationality, proclaimed that a restricted priestly class was a later expedient. The primitive formation crops out here, as witness that, even where hid beneath later deposits, it underlies them all.
