Talmud su Genesi 27:29

It is stated: One answers Amen after a Gentile who recited a benediction for the Eternal, [but if he recited a benediction with the Name one does not answer¹⁸²The text in parenthesis is from the Rome manuscript; it seems that it is missing from the Leyden manuscript and the Venice print because here also, the final clause “one answers only if one heard the entire benediction” is missing since it is implied by the Mishnah. The complete text is that of most sources of the Tosephta (Berakhot 5:21). The correct interpretation seems to be that given by R. Saul Lieberman in Tosephta kifshutah: Since the Gentile is not subject to our rules, if he praises the Eternal, one answers after him Amen. But if he uses a Jewish formula, one may not answer after him Amen unless one has ascertained that he conformed with our rules..] Rebbi Tanḥuma said, if a Gentile blesses you, answer after him Amen since it is written (Deut. 7:14) “You shall be blessed by all peoples.” A Gentile met Rebbi Joshua and blessed him. He answered: The word about you has already been said. He met a second one who cursed him; he answered: The word about you has already been said. His students said to him: Rebbi, did you say to the one what you said to the other? He said to them, so it is written (Gen. 27:29): “Those who curse you are cursed, but those who bless you are blessed.”

Rebbi Hoshaya stated: One answers Amen even if he did not eat, but he may not say: “Let us praise Him, of Whose bounty we ate,” except if he did eat. It is stated: “One answers neither an orphan Amen, nor a plucked Amen. Ben Azai said, if one answered an orphan Amen, may his children be orphans; hurried, may the end of his days be hurried; plucked, may his soul be plucked off. For a long Amen, they lengthen his days and years in a good way. What is an orphan Amen? Rebbi Huna said, that is one who is obligated to recite a blessing, he answers Amen, and is not conscious for what he answered Amen. It is stated: One answers Amen after a Gentile who recited a benediction for the Eternal. By the Name, one does not answer Amen after him. Rebbi Tanḥuma said, if a Gentile blesses you, answer after him Amen since it is written⁴⁰⁷Deut. 7:14. You shall be blessed by all peoples. A Gentile met Rebbi Ismael and blessed him. He answered: The word about you has already been said. He met a second one who cursed him; he answered: The word about you has already been said. His students said to him: Rebbi, did you say to the one what you said to the other? He said to them, so it is written⁴⁰⁸Gen. 27:29. Those who curse you are cursed, but those who bless you are blessed.

¹³¹It seems that the original of this paragraph is in Berakhot8:9. Rebbi Hoshaya stated: One answers Amen even if he did not eat¹³²A person hearing other people reciting Grace has to say Amen; obviously he cannot participate in reciting part of the text; cf. Berakhot7:2., but he may not say: “Let us praise Him, of Whose bounty we ate,” except if he did eat. It is stated¹³³Tosephta Megillah3:27, Babli Berakhot 47a.: “One answers neither an orphan Amen, nor a plucked¹³⁴Amen not completely pronounced.
The other sources have here an addition: “Ben Azai said, if one answered an orphan Amen, may his children be orphans; hurried, may the end of his days be hurried; plucked, may his soul be plucked off. For a long Amen, they lengthen his days and years in a good way.” Amen. What is an orphan Amen? Rebbi Huna said, that is one who is obligated to recite a blessing, he answers Amen, and is not conscious for what he answered Amen. It is stated: One answers Amen after a Gentile who recited a benediction for the Eternal, but if he recited a benediction with the Name one does not answer¹³⁵Since the Gentile is not subject to our rules, if he praises the Eternal, one answers after him Amen. But if he uses a Jewish formula one may not answer after him Amen unless one has ascertained that he conformed with our rules (S. Liebermann.). Rebbi Tanḥuma said, if a Gentile blesses you, answer after him Amen since it is written¹³⁶Deut. 7:14. You shall be blessed by all peoples. A Gentile met Rebbi Ismael and blessed him. He answered: The word about you has already been said. He met a second one who cursed him; he answered: The word about you has already been said. His students said to him: Rebbi, did you say to the one what you said to the other? He said to them, so it is written¹³⁷Gen. 27:29. Those who curse you are cursed, but those who bless you are blessed.
