What does “widen your mouth and I will fill it” mean?
By Rabbi Shalom Landau.
Rabbi Landau explains the verse “Harchev picha va'amaleihu,” widen your mouth and I will fill it, as Hashem's promise: “You expand your desire, I'll expand your delivery.” The widening is our part; the filling is His.
It rests on how he understands blessing. Hashem created a world of abundance, but “he only gives vessel that can hold the blessings.” So He plants desire in a person, “not to tease you, but to shape you.” Following that desire with faith and work is how the vessel grows, until “you become someone heaven can trust with more.”
That is why he says financial desire is not a test. “He gave it to direct you,” and as much desire as you have, that is part of your mission.
In A Soul at Peace, Rabbi Landau writes that “open wide” is a command to do inner work: widen your vessel by working on your character traits and building your trust in Hashem. The blessing is always there, but it flows only into a vessel that is ready to receive it. He also calls giving charity “open wide” in actual practice.
