וַתֹּ֨אמֶר שָׂרַ֜י אֶל־אַבְרָ֗ם הִנֵּה־נָ֞א עֲצָרַ֤נִי יְהוָה֙ מִלֶּ֔דֶת בֹּא־נָא֙ אֶל־שִׁפְחָתִ֔י אוּלַ֥י אִבָּנֶ֖ה מִמֶּ֑נָּה וַיִּשְׁמַ֥ע אַבְרָ֖ם לְק֥וֹל שָׂרָֽי׃
Dijo, pues, Sarai á Abram: Ya ves que SEÑOR me ha hecho estéril: ruégote que entres á mi sierva; quizá tendré hijos de ella. Y atendió Abram al dicho de Sarai.
Mishnah Nazir
[If one says,] “Behold, I am a nazirite when I shall have a son,” and son is born to him, he becomes a nazirite. If the child is a daughter, or a tumtum, or an hermaphrodite, he does not become a nazirite. If he said, “When I shall have a child,” then even if it is a daughter, or a tumtum, or an hermaphrodite, he becomes a nazirite.
