Хасидус к Берешит 43:29

וַיִּשָּׂ֣א עֵינָ֗יו וַיַּ֞רְא אֶת־בִּנְיָמִ֣ין אָחִיו֮ בֶּן־אִמּוֹ֒ וַיֹּ֗אמֶר הֲזֶה֙ אֲחִיכֶ֣ם הַקָּטֹ֔ן אֲשֶׁ֥ר אֲמַרְתֶּ֖ם אֵלָ֑י וַיֹּאמַ֕ר אֱלֹהִ֥ים יָחְנְךָ֖ בְּנִֽי׃

И он поднял глаза и увидел Вениамина, брата его, мать его'с сыном, и сказал: 'Это ваш младший брат, о котором вы говорили мне?' И сказал он: 'Боже, будь милостив к тебе, сын мой.'
