Exodus 16:35
And the children of Israel did eat manna forty years, until they came to a land inhabited; they did eat manna, until they came unto the borders of the land of Canaan. And the children of Israel did eat manna forty years, until they came to a land inhabited; they did eat manna, until they came unto the borders of the land of Canaan.
The children of Israel ate manna for forty years in the wilderness, until they came to an inhabited land and to the borders of the land of Canaan. The giving of the bread from heaven was God's answer to stop their murmuring. That bread was angels' food, provided through angels, the best food that could possibly be given.
Through the manna God worked a weekly miracle to teach that the Sabbath was sacred and must be kept. The daily provision reminded Israel of His unfailing care and tender love, and taught that His promise made them as secure from want as if they were already surrounded by the waving grain of Canaan. The manna is a type of Christ, the bread from heaven who gives life to the world, and the hidden manna is promised to those who overcome.
The feeding with manna was part of an all-embracing education covering all habits of life and well-being under divine solicitude and law, in which even in providing food God sought their highest good. It was of a nature to promote physical, mental, and moral strength, so that despite the hardships of wilderness life there was not a feeble one in all their tribes. Yet though they had angels' food to eat, it did not satisfy them.
God Himself gave the manna for forty years, proving He has skill and understanding for His people and still cares for His children. He also kept their shoes and clothing from growing old and worn during those forty years. Practical questions about food preparation and use need not be settled in every detail at once, for if people place themselves in right relation to Him and commune with Him daily they will be taught by Him, receive His blessing, pray for divine enlightenment, learn from one another, and develop gradually as they advance. Present guidance can be expected from the same God, so those who place themselves in right relation to Him and commune with Him daily will be taught by Him and receive His blessing in working out practical perplexities step by step as they advance.
