It is not too much to say that if modern theology were not affected by this ancient problem, if we regarded the creed of the Hebrews simply as we look at the mythologies of other peoples, there would be no more doubt that the early Jews believed in propitiatory sacrifice than that Phoenicians did. We should simply admire the purity, the absence of cruel and degrading accessories, with which this most perilous and yet humbling and admonitory doctrine was held in Israel.
The Christian applications of this doctrine must be considered along with the whole question of the typical character of the history. But it is not now premature to add, that even in the Old Testament there is abundant evidence that the types were semi-transparent, and behind them something greater was discerned, so that after it was written "Bring no more vain oblations," Isaiah could exclaim, "The Lord hath laid on Him the iniquity of us all. He was led as a lamb to the slaughter. When Thou shalt make His soul a trespass-offering He shall see His seed" (Isa. i. 13, liii. 6, 7, 10). And the full power of this last verse will only be felt when we remember the statement made elsewhere of the principle which underlay the sacrifices: "the life (_or_ soul) of the flesh is in the blood, and I have given it to you upon the altar to make atonement for your souls; for it is the blood that maketh atonement by reason of the life" (_or_ "soul"--Lev. xvii. 11, R.V.) It is even startling to read the two verses together: "Thou shalt make His soul a trespass-offering;" "The blood maketh atonement by reason of the soul ... the soul of the flesh is in the blood."[22]
It is still more impressive to remember that a Servant of Jehovah has actually arisen in Whom this doctrine has assumed a form acceptable to the best and holiest intellects and consciences of ages and civilisations widely remote from that in which it was conceived.
Another doctrine preached by the passover to every Jew was that he must be a worker together with God, must himself use what the Lord pointed out, and his own lintels and doorposts must openly exhibit the fact that he laid claim to the benefit of the institution of the Lord Jehovah's passover. With what strange feelings, upon the morrow, did the orphaned people of Egypt discover the stain of blood on the forsaken houses of all their emancipated slaves!
The lamb having been offered up to God, a new stage in the symbolism is entered upon. The body of the sacrifice, as well as the blood, is His: "Ye shall eat it in haste, it is the Lord's passover" (ver. 11). Instead of being a feast of theirs, which they share with Him, it is an offering of which, when the blood has been sprinkled on the doors, He permits His people, now accepted and favoured, to partake. They are His guests; and therefore He prescribes all the manner of their eating, the attitude so expressive of haste, and the unleavened "bread of affliction" and bitter herbs, which told that the object of this feast was not the indulgence of the flesh but the edification of the spirit, "a feast unto the Lord."
And in the strength of this meat they are launched upon their new career, freemen, pilgrims of God, from Egyptian bondage to a Promised Land.
It is now time to examine the chapter in more detail, and gather up such points as the preceding discussion has not reached.
(Ver. 1.) The opening words, "Jehovah spake unto Moses and Aaron in the land of Egypt," have all the appearance of opening a separate document, and suggest, with certain other evidence, the notion of a fragment written very shortly after the event, and afterwards incorporated into the present narrative. And they are, in the same degree, favourable to the authenticity of the book.
