Our Sages teach that it is an ancestral segula for Parnassa (material sustenance) to read, on the Tuesday when Parashat Beshalach falls, the Torah passage that speaks of the Manna.

Concretely, this means reading from chapter 16, verse 4, to verse 36, of the book of Shemot (Exodus). After the reading, one prays to Hashem to grant the material needs necessary for one's life.

Translation: May it be Your will, Hashem our G-d and G-d of our fathers, that You provide sustenance for all Your people the House of Israel, as well as my sustenance and that of the members of my household among them, with ease and not with hardship, with honor and not with shame, in a permissible manner and not a forbidden one, so that we may perform Your service and study Your Torah, just as You nourished our fathers with manna in the wilderness, in an arid and desolate land.

Hashem tells Moshe that He will rain down bread from heaven. But this gift is also a test: the people must learn to gather only one day's portion at a time, without hoarding for tomorrow, so as to show their trust in divine providence.

Hashem said to Moshe: "Behold, I will rain down bread for you from heaven. The people shall go out and gather each day's portion on its day, so that I may test them whether they will follow My Torah or not."

Moshe and Aharon tell the people that their complaints, in truth directed against Hashem Himself, will be answered: meat in the evening, bread in the morning. Then, in the wilderness, the glory of Hashem appears in the cloud.

In the evening, quail came up and covered the camp, and in the morning there was a layer of dew around the camp. When the dew rose, behold, upon the surface of the wilderness there was something fine, flaky, fine as frost on the ground.

The children of Israel saw it and said to one another: "What is it (Man hu)?" — for they did not know what it was. Moshe said to them: "This is the bread that Hashem has given you to eat."

Hashem prescribes gathering one omer per person, each according to his need, for those in his tent. The people obey: some gather much, others little.

When they measured with the omer, he who gathered much had no surplus, and he who gathered little lacked nothing; each had gathered exactly according to what he could eat.

But they did not listen to Moshe, and some men left of it until morning; it bred worms and became foul. Moshe was angry with them.

On the sixth day, the people gather a double portion; the princes of the congregation come to report this to Moshe, who reveals that it is meant to announce Shabbat.

Moshe said: "Eat it today, for today is a Sabbath to Hashem; today you will not find it in the field."

See that Hashem has given you the Sabbath; therefore He gives you on the sixth day bread for two days. Let each remain in his place; let no one go out of his place on the seventh day.

The house of Israel called it "manna." It was like coriander seed, white, and its taste was like a wafer made with honey.

Moshe said: "This is what Hashem has commanded: let a full omer of it be kept for your generations, so that they may see the bread with which I fed you in the wilderness." He then told Aharon: "Take a jar, put a full omer of manna in it, and place it before Hashem, to be kept for your generations."

The children of Israel ate the manna for forty years, until they came to an inhabited land; they ate it until they came to the border of the land of Canaan. The omer is a tenth of an ephah.

Translation: May it be Your will, Hashem my G-d and G-d of my fathers, that You provide for me and my household all our needs, for every day and every hour, from Your good and generous hand, and not sparingly according to our merits, but from the abundance of Your kindness. May our sustenance, that of our household and of our descendants, be entrusted in Your hand, and not in the hand of flesh and blood.

May Hashem grant abundant Parnassa to all the people of Israel!
