Manna - Use and Function

Use and Function

Until they reached Canaan, the Israelites are implied by some passages in the Bible to have eaten only manna during their desert sojourn, despite the availability of milk and meat from the livestock with which they traveled, and the references to provisions of fine flour, oil, and meat, in parts of the journey's narrative.

As a natural food substance, manna would produce waste products; but in classical rabbinical literature, as a supernatural substance, it was held that manna produced no waste, resulting in no defecation among the Israelites until several decades later, when the manna had ceased to fall. Modern medical science suggests the lack of defecation over such a long period of time would cause severe bowel problems, especially when other food later began to be consumed again. Classical rabbinical writers say that the Israelites complained about the lack of defecation, and were concerned about potential bowel problems.

Many Christian vegetarians say that God had originally intended man would not eat meat because plants cannot move and killing them would not be sinful: manna, a nonmeat substance, is used to support this theory. Further, when the people complained and wished for quail, God gave it to them, but they apparently still complained and some greedily gathered the quail. "While the meat was still between their teeth, before it was chewed, the anger of the Lord was kindled against the people."

Food was not manna's only use; one classical rabbinical source states that the fragrant odor of manna was used in an Israelite perfume.
