Comentario sobre Berajot 9:3
בָּנָה בַיִת חָדָשׁ, וְקָנָה כֵלִים חֲדָשִׁים, אוֹמֵר בָּרוּךְ שֶׁהֶחֱיָנוּ. מְבָרֵךְ עַל הָרָעָה מֵעֵין הַטּוֹבָה, וְעַל הַטּוֹבָה מֵעֵין הָרָעָה. הַצּוֹעֵק לְשֶׁעָבַר, הֲרֵי זוֹ תְּפִלַּת שָׁוְא. כֵּיצַד. הָיְתָה אִשְׁתּוֹ מְעֻבֶּרֶת, וְאָמַר, יְהִי רָצוֹן שֶׁתֵּלֵד אִשְׁתִּי זָכָר, הֲרֵי זוֹ תְּפִלַּת שָׁוְא. הָיָה בָא בַדֶּרֶךְ וְשָׁמַע קוֹל צְוָחָה בָּעִיר, וְאָמַר יְהִי רָצוֹן שֶׁלֹּא יִהְיוּ אֵלּוּ בְּנֵי בֵיתִי, הֲרֵי זוֹ תְּפִלַּת שָׁוְא:
Si construyó una nueva casa o compró nuevos vasos, dice "shehecheyanu" ("que nos mantuvo en la vida, etc.") [Ya sea que tenga o no otros vasos del mismo tipo, dice "shehecheyanu"]. sobre un mal en el que el bien es inherente [La gemara explica: como cuando los campos de uno se inundan y pierde la cosecha de este año. Aunque el suelo está saturado y el campo se hizo más fértil en los años venideros, ahora, sin embargo, es malo, y él bendice "dayan ha'emeth"], y sobre un bien en el que un mal está presente [como cuando uno encuentra Un objeto perdido. A pesar de que es malo para él, porque si el rey lo oye, será golpeado y torturado y se le quitará el objeto, ahora, sin embargo, es bueno y bendice "hatov vehametiv"]. Clamar por lo pasado constituye una oración vana. [Si uno reza por lo que ya sucedió, esta es una oración en vano, por "lo que ha sido"), como en la oración: "Que sea tu voluntad que mi esposa tenga un hijo", cuando ya está embarazada; o, como cuando uno regresa de un viaje y escucha los lamentos dentro de la ciudad, reza: "Que sea tu voluntad que no venga de mi casa".
Bartenura on Mishnah Berakhot
English Explanation of Mishnah Berakhot
One who blesses over the evil as he blesses over the good or over the good as he blesses over evil; one who cries over the past, behold this is a vain prayer.
How so? If his wife was pregnant and he says, “May it be his will that my wife bear a male child,” this is a vain prayer.
If he is coming home from a journey and he hears a cry of distress in the town and says, “May it be his will that this is not be those of my house,” this is a vain prayer.
Section one: This is the familiar blessing “shehecheyanu” which we recite upon eating new foods, receiving new things, at the beginning of holidays and at certain other events.
Section two: This is a difficult clause to explain. Albeck explains that this refers to one who tries to bless over something bad the blessing that he should say for the good, “Blessed be He that is good and grants good.” What he is trying to do is be hopeful that from something bad will come something good. Alternatively, he blesses the blessing for the bad, “Blessed be the true judge” because he fears that something bad will come from the good. These are both vain prayers because after the event has already happened it cannot be changed. Thus these are both specific cases of one who is crying over the past. Prayers are legitimate only if they are recited in anticipation of an event that has not yet occurred. The Rambam explains that this mishnah mandates reciting the blessing over the good for something that is now good even if it might eventually be bad. Similarly, one must recite the blessing over bad for something that is now bad even though it might eventually be good. As in Albeck’s explanation, the focus is on the present and not something that might change in the future.
Sections three and four: These are both examples of “crying over the past.” Once the child’s sex has been determined it cannot change. There is no use in crying out to God in hope that the house that is under distress is not one’s house because whatever house it is has already been determined. Once something has already happened one must be reconciled with one’s fate.
