Suppose all the grocery stores would close down, all the fruit stores and the butcher shops would all close down, all the restaurants would close down let’s say for a month’s time, and there’s no place to go for food. What would happen to us? Imagine such a scenario. In one month chas v’shalom we’d be over, finished.
It’s a deception. It comes straight from Hashem
And Yisrael in the midbar (desert) had absolutely no source of food. They didn’t import apples let’s say from Idaho, or potatoes from Idaho or watermelons from South America. They didn’t import anything. On the spot they had to live on what they had on the spot. What did they have on the spot? Only what fell. Every day there fell mann, and the mann was entirely unexpected. That’s what the word mann means: mah hu; mann means what is this.
Therefore when we sit down to eat, although we think we know where it came from — the grocery store, the bakery, the butcher, the farms — you must know it’s a deception. It comes straight from Hashem. It’s important, that lesson. So as you see bread on your table, it’s Hashem Who dropped mann on your table.
"Poseiach es yadecha, u’masbia l’chol chai ratzon — You open up your hand and You’re satiating the desires of all the living” (Ashrei). You are doing with Your hand. So let’s say you’re in the restaurant and a waiter hands you something, or your wife is handing you at the table, that hand is the hand of Hashem stretched out to you. — Aspects of Bitachon (#937)
