The meaning of manna in Hebrew is the following: the food that God provided for you to eat.
It was white in color and tasted like pancakes mixed with honey.
God provided manna, and also gave rules:
It should be eaten on the same day; if left over to the next day, it will get infested with bugs and go bad.
The most amazing thing is that the Israelites collected manna in this way, some collected more and some collected less.
Those who collect more have no surplus, and those who collect less have no shortage.
It seems like the life of a Christian, where there is no surplus for those who earn more and enough for those who earn less.
So we don't need to envy others' wealth.
Don't waste time envying others, focus on becoming better yourself.
