No later inventor would have known how to say so little, much less to make that little harmonise so exactly with the lessons meant to be suggested by the wild and solemn solitudes into which they were now plunged. And now the Lord Himself repeats the promise of relief, but first solemnly announces that He is not heedless of their ill-behaviour while He tolerates it. The question is suggested, although not asked, How long will His forbearance last? Well for them if they learn the lesson, and “know that I am Jehovah your God,” mindful of their needs, entitled to their fealty. In the evening, therefore, came a flight of quails; and in the morning they found a small round thing, small as the hoar-frost, upon the ground. _MANNA._ xvi. 15–36. The manna which miraculously supplied the wants of Israel was to them an utterly strange food, the use of which they had to learn. Thus it was another means of severing their habitual course of life and association of ideas from their degraded past. And while we may not press too far the assertion that it was the “corn of heaven” and “angels’ food” (_i.e._ “the bread of the mighty”—Psalm lxxviii. 24–5, R.V.), yet the narrative shows, even without help from later scriptures, that it was calculated to sustain their energies and yet to leave their appetites unstimulated and unpampered. For they were now called to purer joys than those of the senses—to liberty, a divine vocation, the presence of God, the revelation of His law and the unfolding of His purposes. Failing to rise to these heights, they fell far, murmured again, and perished by the destroyer, not merely to avenge the petulance of an hour, but for all that it betrayed, for treason to their vocation and radical inability to even comprehend its meaning. In the language of modern science, it answered to Nature’s rejection of the unfit. Their calling was thus, though under very different forms, that which the apostles found so hard, yet did not quite refuse: it was to mind the things of God and not the things of men. It is well known that the manna of the Israelites bore some resemblance to a natural product of the wilderness, still exuded by certain plants during the coolness of the night, and formerly more plentiful than now, when all vegetation has been ruthlessly swept away by the Bedouin. But the differences are much greater than the resemblance. The natural product is a drug, and not a food; it is gathered only during some weeks of summer; it is not liable to speedy corruption, nor could there be any reason for preserving a specimen of this common product in the ark; it could not have sufficed, however aided by their herds and flocks, to feed one in a hundred of the Hebrew multitudes, even during the season of its production; nor could it have ceased on the same day when they ate the first ripe corn of Canaan.
