Exodus 16:32-33

32Then Moses said, “This is what the Lord has commanded: Fill a two-quart container with manna to preserve it for your descendants. Then later generations will be able to see the food I gave you in the wilderness when I set you free from Egypt.”

33Moses said to Aaron, “Get a jar and fill it with two quarts of manna. Then put it in a sacred place before the Lord to preserve it for all future generations.”
