A certain frum yid (“Torah observant jew”) I had visited to ask for tzedakah told me, when I asked him if he could help me: “Today until Friday there are critical meetings about my portion in Parnasah/financial sustenance for me to help you and others”. I wished him hatzlacha rabbah/great success and left him. He did not help me this time, but I went on my way, happy and confident Hashem would care for me. On the way out, after thinking on our conversation, I wrote him a note and left it at his office’s entrance desk: Dear Reb Fivish, the millui (“spelling out”) of צדקה tzedakah is צדי דלת קוף הא, which has gematria 730. This is the same numerical value as what is said in the verse of parashat Toledot: מטעמים כאשר matamim kaasher, “savoury food” (Bereshit 27:14). Now, I will be praying for you to be served this most “savory food”. And since you have fear of G-d, I know you will serve holy shirayim* to us all, for this is something אהב אביו ahev aviv, “his ‘Father in Heaven’ will love”**.
* A popular Chassidic custom to endeavor to obtain food from which a Rebbe has partaken from. This practice is referred to as shirayim, meaning “leftovers”.
** The pasuk mentioned ends: מטעמים כאשר אהב אביו matamim kaasher ahev aviv. The last part is here interpreted (and the verb tense changed) as meaning that Hashem (Av/Father in Heaven) approves of this sharing in the food/money.
