יִפְתַּ֣ח יְהוָ֣ה ׀ לְ֠ךָ אֶת־אוֹצָר֨וֹ הַטּ֜וֹב אֶת־הַשָּׁמַ֗יִם לָתֵ֤ת מְטַֽר־אַרְצְךָ֙ בְּעִתּ֔וֹ וּלְבָרֵ֕ךְ אֵ֖ת כָּל־מַעֲשֵׂ֣ה יָדֶ֑ךָ וְהִלְוִ֙יתָ֙ גּוֹיִ֣ם רַבִּ֔ים וְאַתָּ֖ה לֹ֥א תִלְוֶֽה׃
Otworzy ci Wiekuisty skarbnicę Swą dobroczynną, - niebo, aby dać deszcz ziemi twej w czasie swoim, i by błogosławić wszelkiej sprawie rąk twoich, że będziesz wypożyczał wielu narodom, sam zaś nie pożyczał.
Sha'arei Kedusha
After you finish your meal and have been physically and spiritually nourished through eating and studying, do not be unappreciative. Bless HaShem-יהו"ה for all the goodness He has sustained you with, by reciting the blessings after meals with great joy, like a person who has just received a precious gift,270Zohar II 218 as we say in the blessing,271In the grace after meals (Birkhat HaMazon) “for the Torah that you taught us and for the consumption of food that you sustain us with.” In the merit of doing this, HaShem-יהו"ה will open His treasury of goodness272Deuteronomy 28:12 to you and will sustain you always.
