(Ver. 8.) The use of unleavened bread is distinctly said to be in commemoration of their haste—“for thou camest out of Egypt in haste” (Deut. xvi. 3)—but it does not follow that they were forced by haste to eat their bread unleavened at the first. It was quite as easy to prepare leavened bread as to provide the paschal lamb four days previously.
We may therefore seek for some further explanation, and this we find in the same verse in Deuteronomy, in the expression “bread of affliction.” They were to receive the meat of passover with a reproachful sense of their unworthiness: humbly, with bread of affliction and with bitter herbs.
Moreover, we learn from St. Paul that unleavened bread represents simplicity and truth; and our Lord spoke of the leaven of the Pharisees and of Herod (Mark viii. 15). And this is not only because leaven was supposed to be of the same nature as corruption. We ourselves always mean something unworthy when we speak of _mixed_ motives, possible though it be to act from two motives, both of them high-minded. Now, leaven represents mixture in its most subtle and penetrating form.
The paschal feast did not express any such luxurious and sentimental religionism as finds in the story of the cross an easy joy, or even a delicate and pleasing stimulus for the softer emotions, “a very lovely song of one that hath a pleasant voice, and playeth well on an instrument.” No, it has vigour and nourishment for those who truly hunger, but its bread is unfermented, and it must be eaten with bitter herbs.
(Ver. 9.) Many Jewish sacrifices were “sodden,” but this had to be roast with fire. It may have been to represent suffering that this was enjoined. But it comes to us along with a command to consume all the flesh, reserving none and rejecting none. Now, though boiling does not mutilate, it dissipates; a certain amount of tissue is lost, more is relaxed, and its cohesion rendered feeble; and so the duty of its complete reception is accentuated by the words “not sodden at all with water.” Nor should it be a barbarous feast, such as many idolatries encouraged: true religion civilises; “eat not of it at all raw.”
(Ver. 10.) Nor should any of it be left until the morning. At the first celebration, with a hasty exodus impending, this would have involved exposure to profanation. In later times it might have involved superstitious abuses. And therefore the same rule is laid down which the Church of England has carried on for the same reasons into the Communion feast—that all must be consumed. Nor can we fail to see an ideal fitness in the precept. Of the gift of God we may not select what gratifies our taste or commends itself to our desires; all is good; all must be accepted; a partial reception of His grace is no valid reception at all.
