Mattityahu 6:31-33

Therefore, do not have a LEV ROGEZ, saying, What might we eat? or What might we drink? or With what might we clothe ourselves? For all these things the Goyim strive. For your Av shbaShomayim bavorn (anticipates) that you need all these things. But seek first the Malchut HASHEM and the Tzidkat HASHEM, and all these things will be added to you.
