Once at twilight, Rabbi Hanina ben Dosa saw that his daughter was sad.
He asked: My daughter, why are you sad?
She answered: I mistook a vessel of vinegar for one of oil and lit the Sabbath lamp from it.
He said: My daughter, why should you care? He who told oil to burn will tell vinegar to burn.
They said it continued burning all day until they took a flame from it for Havdalah. (Babylonian Talmud, Taโ€™anit 25a, freely translated from Aramaic)

The message of this beautiful story is the plain meaning of a familiar verse in our portion, in Mosesโ€™ commandments speech on Moabโ€™s plains before entering the land:

And He afflicted thee, and suffered thee to hunger, and fed thee with manna, which thou knewest not, neither did thy fathers know; that He might make thee know that man doth not live by bread only, but by every thing that proceedeth out of the mouth of the LORD doth man live. (Deuteronomy 8:3)

What did Moses mean by โ€œman doth not live by bread only, but by every thing that proceedeth out of the mouth of the LORD doth man liveโ€?

His account of manna differs greatly from Numbers, which praises its culinary properties and wonderful flavor:

Now the manna was like coriander seed, and the appearance thereof as the appearance of bdellium. The people went about, and gathered it, and ground it in mills, or beat it in mortars, and seethed it in pots, and made cakes of it; and the taste of it was as the taste of a cake baked with oil. (Numbers 11:7โ€“8)

In Mosesโ€™ speech, however, manna was not food. Eating it was affliction that caused hunger, as also stated later:

who fed thee in the wilderness with manna, which thy fathers knew not, that He might afflict thee. (Deuteronomy 8:16)

The lesson โ€“ โ€œthat He might make thee knowโ€ โ€“ is that bread is not indispensable to life: โ€œman doth not live by bread only.โ€ Something not food, without nutritional value, like manna, can sustain us if the LORD decrees it to be food: โ€œby every thing that proceedeth out of the mouth of the LORD doth man liveโ€!

Ibn Ezra explains:

โ€œThat proceedeth out of the mouth of the LORDโ€: like that which He decreed โ€ฆ The meaning of โ€œman doth not live by bread onlyโ€ is rather by the power, or together with the power, that comes from the higher realms at the LORDโ€™s command. This is the explanation of โ€œthat proceedeth out of the mouth of the LORD.โ€ The evidence is that you ate no bread โ€“ and lived.
