God might as easily have provided them with flesh as with manna, but a restriction was placed upon them for their good. It was His purpose to supply them with food better suited to their wants than the feverish diet to which many had become accustomed in Egypt. The perverted appetite was to be brought into a more healthy state, that they might enjoy the food originally provided for man—the fruits of the earth, which God gave to Adam and Eve in Eden. It was for this reason that the Israelites had been deprived, in a great measure, of animal food. (PP 378.1) MC VC

Satan tempted them to regard this restriction as unjust and cruel. He caused them to lust after forbidden things, because he saw that the unrestrained indulgence of appetite would tend to produce sensuality, and by this means the people could be more easily brought under his control. The author of disease and misery will assail men where he can have the greatest success. Through temptations addressed to the appetite he has, to a large extent, led men into sin from the time when he induced Eve to eat of the forbidden fruit. It was by this same means that he led Israel to murmur against God. Intemperance in eating and drinking, leading as it does to the indulgence of the lower passions, prepares the way for men to disregard all moral obligations. When assailed by temptation, they have little power of resistance. (PP 378.2) MC VC

God brought the Israelites from Egypt, that He might establish them in the land of Canaan, a pure, holy, and happy people. In the accomplishment of this object He subjected them to a course of discipline, both for their own good and for the good of their posterity. Had they been willing to deny appetite, in obedience to His wise restrictions, feebleness and disease would have been unknown among them. Their descendants would have possessed both physical and mental strength. They would have had clear perceptions of truth and duty, keen discrimination, and sound judgment. But their unwillingness to submit to the restrictions and requirements of God, prevented them, to a great extent, from reaching the high standard which He desired them to attain, and from receiving the blessings which He was ready to bestow upon them. (PP 378.3) MC VC
