וַיֵּרָ֨א אֵלָ֤יו יְהוָה֙ בַּלַּ֣יְלָה הַה֔וּא וַיֹּ֕אמֶר אָנֹכִ֕י אֱלֹהֵ֖י אַבְרָהָ֣ם אָבִ֑יךָ אַל־תִּירָא֙ כִּֽי־אִתְּךָ֣ אָנֹ֔כִי וּבֵֽרַכְתִּ֙יךָ֙ וְהִרְבֵּיתִ֣י אֶֽת־זַרְעֲךָ֔ בַּעֲב֖וּר אַבְרָהָ֥ם עַבְדִּֽי׃
그 밤에 여호와께서 그에게 나타나 가라사대 나는 네 아비 아브라함의 하나님이니 두려워 말라 내 종 아브라함을 위하여 내가 너와 함께 있어 네게 복을 주어 네 자손으로 번성케 하리라 하신지라
Tosefta Berakhot
The blessing after the meal is an obligation from the Torah, as it says “And you will eat and be sated, and you shall bless the Lord, your God, for the good land He has given you.” (Devarim 8:10) ’And you will eat and be sated, and you shall bless’ this refers to the blessing after the meal. ‘the Lord, your God’ refers to the first blessing on the land. ‘the good land’ this refers to Jerusalem, as it says “…this good mountain and the Lebanon.” (Devarim 3:25) ‘He has given you’ this refers to the blessing of ‘who is good and does good.’ From where do we learn that just as one is obligated to make a blessing before eating, so too they are obligated to make one after eating? The verse says ‘He has given you,’ meaning from the moment He has given it to you. From where do we learn that we bless even on the mountains and the hills? The verse says ‘on the land.’ From where do we learn that we bless even on the Torah and the commandments? The verse says ‘He has given you,’ and it says elsewhere “…and I will give you the stone tablets…” (Shemot 24:12) R’ Meir says ‘from where do we learn that just as one blesses on the good, so too they bless on the bad? The verse says ‘the Lord, your God…has given you’ “Your God,” meaning, “your Judge.” Bless Him for every judgement He passes on you, be it for the good or bad.
