When Israel complained of hunger, the LORD sent quail in the evening and bread from heaven each morning. The people called it manna, gathered a daily portion, and kept the seventh day as a Sabbath (Exodus 16:1-36).
1On the fifteenth day of the second month after they had left the land of Egypt, the whole congregation of Israel set out from Elim and came to the Desert of Sin, which is between Elim and Sinai. 2And there in the desert they all grumbled against Moses and Aaron. 3“If only we had died by the LORD’s hand in the land of Egypt!” they said. “There we sat by pots of meat and ate our fill of bread, but you have brought us into this desert to starve this whole assembly to death!”
God fed Israel with manna in the wilderness. Paul calls the food they ate "spiritual food."
They all ate the same spiritual food
Exodus 16 records the bread that God gave Israel in the wilderness. First Corinthians 10:3 says that Israel ate the same spiritual food.
Paul quotes the manna account. The one who gathered much had no excess, and the one who gathered little had no shortage.
It is not our intention that others may be relieved while you are burdened, but that there may be equality. At the present time, your surplus will meet their need, so that in turn their surplus will meet your need. Then there will be equality. As it is written: “He who gathered much had no excess, and he who gathered little had no shortfall.”
Exodus 16:17-18 says that some Israelites gathered more manna and some less, yet each had what was needed. Second Corinthians 8:15 introduces the same words with, "As it is written."
