וַיְצַ֣ו פַּרְעֹ֔ה לְכָל־עַמּ֖וֹ לֵאמֹ֑ר כָּל־הַבֵּ֣ן הַיִּלּ֗וֹד הַיְאֹ֙רָה֙ תַּשְׁלִיכֻ֔הוּ וְכָל־הַבַּ֖ת תְּחַיּֽוּן׃ (ס)
E Paroh ordenou a todo o seu povo, dizendo: "Todo filho que nascer, lançai-o no rio, mas toda filha, deixai-a viver." {פ}
Mishnah Nedarim
One who vows [not to benefit] from those born may [benefit] from those to be born; from those to be born, he may not [benefit] from those born. Rabbi Meir permits [him to benefit] even from those to be born; But the Sages say: he meant all whose nature it is to be born.
