The Zohar teaches that the Jews collected their daily manna with simple faith – no one had any doubt that the manna would be there. They went outside every single day with absolute trust in Hashem that he would provide for their every single need.

Today, the Tuesday of Parshas Beshalach, there is a well known segula for parnasah – say Parshas HaMon “shnayim mikra v’echad targum” (2 times the pasuk and 1 time the Targum Unkelos). Here is a link to the text http://www.tefillos.com/parshas_hamon.asp

But yesterday you wrote that the reason the Man fell every dayw as because people had to worry about their daily sustenance! Contradiction?
Let’s say I know Hashem will always take care of me, does that mean i shouldn’t ask for His continued support?
