The punishment of those who complained is spoken of as swift and terrible. "The fire of the Lord burnt among them, and devoured in the uttermost part of the camp." This judgment falls under a principle assumed throughout the whole book, that disaster must overtake transgressors, and conversely that death by pestilence, earthquake, or lightning is invariably a result of sin. For the Israelites this was one of the convictions that maintained a sense of moral duty and of the danger of offending God. Again and again in the wilderness, where thunderstorms were common and plagues spread rapidly, the impression was strongly confirmed that the Most High observed everything that was done against His will. The journey to Canaan brought in this way a new experience of God to those who had been accustomed to the equable conditions of climate and the comparative health enjoyed in Egypt. The moral education of the people advanced by the quickening of conscience in regard to all that befell Israel. From the disaster at Taberah the narrative passes to another phase of complaint in which the whole camp was involved. The dissatisfaction began amongst the "mixed multitude"--that somewhat lawless crowd of low-caste Egyptians and people of the Delta and the wilderness who attached themselves to the host. Among them first, because they had absolutely no interest in Israel's hope, a disposition to quarrel with their circumstances would naturally arise. But the spirit of dissatisfaction grew apace, and the burden of the new complaint was: "We have nought but this manna to look to." The part of the desert into which the travellers had now penetrated was even more sterile than Midian. Hitherto the food had been varied somewhat by occasional fruits and the abundant milk of kine and goats. But pasturage for the cattle was scanty in the wilderness of Paran, and there were no trees of any kind. Appetite found nothing that was refreshing. Their soul was dried away. It was a common belief in our Lord's time that the manna, falling from heaven, very food of the angels, had been so satisfying, so delicious, that no people could have been more favoured than those who ate of it. When Christ spoke of the meat which endureth unto eternal life, the thought of His hearers immediately turned to the manna as the special gift of God to their fathers, and they conceived an expectation that Jesus would give them that bread of heaven, and so prove Himself worthy of their faith. But He replied, "Moses gave you not that bread out of heaven, but My Father giveth you the true bread out of heaven. I am the Bread of Life."
