יִפְתַּ֣ח יְהוָ֣ה ׀ לְ֠ךָ אֶת־אוֹצָר֨וֹ הַטּ֜וֹב אֶת־הַשָּׁמַ֗יִם לָתֵ֤ת מְטַֽר־אַרְצְךָ֙ בְּעִתּ֔וֹ וּלְבָרֵ֕ךְ אֵ֖ת כָּל־מַעֲשֵׂ֣ה יָדֶ֑ךָ וְהִלְוִ֙יתָ֙ גּוֹיִ֣ם רַבִּ֔ים וְאַתָּ֖ה לֹ֥א תִלְוֶֽה׃
Господь откроет тебе Своё доброе сокровище на небе, чтобы дать дождь земли твоей в свое время и благословить всю работу руки твоей; и будешь давать взаймы многим народам, а не будешь брать взаймы.
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.
