וַתֹּ֨אמֶר שָׂרַ֜י אֶל־אַבְרָ֗ם הִנֵּה־נָ֞א עֲצָרַ֤נִי יְהוָה֙ מִלֶּ֔דֶת בֹּא־נָא֙ אֶל־שִׁפְחָתִ֔י אוּלַ֥י אִבָּנֶ֖ה מִמֶּ֑נָּה וַיִּשְׁמַ֥ע אַבְרָ֖ם לְק֥וֹל שָׂרָֽי׃
사래가 아브람에게 이르되 여호와께서 나의 생산을 허락지 아니하셨으니 원컨대 나의 여종과 동침하라 내가 혹 그로 말미암아 자녀를 얻을까 하노라 하매 아브람이 사래의 말을 들으니라
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.
