“Six days you will gather [the manna] and on the seventh day, which is Sabbath there won’t be any.  And it was on the seventh day, some of the people went out to collect and they did not find any.  And Hashem said to Moshe, how long will you refuse to observe my commandments and teachings?  See that Hashem has given you the Sabbath; therefore on the sixth day He gives you bread for two days; let each man remain in his place – let no man leave his place on the seventh day.  So the nation rested on the seventh day.” ~ Exodus 16: 26-30

These verses teach a great lesson – on the Sabbath there is no such thing as making money.  Someone who claims that his busiest day of the week is Sabbath is greatly mistaken.  He will see neither pleasure nor benefit from those “profits.”  While it may seem at first that he is making money, this is not the case.  He will lose it through various seemingly “unnecessary” hardships.  On the contrary, a person who keeps the Sabbath will make much more during the week than he would have otherwise.  This is the way Hashem runs the world – plain and simple.   Hashem does not require the impossible – if He wants us to observe the Sabbath, then He has created a mechanism that enables us to do exactly that.  ~ The Garden of Riches
