וַתִּדֹּ֨ר נֶ֜דֶר וַתֹּאמַ֗ר יְהוָ֨ה צְבָא֜וֹת אִם־רָאֹ֥ה תִרְאֶ֣ה ׀ בָּעֳנִ֣י אֲמָתֶ֗ךָ וּזְכַרְתַּ֙נִי֙ וְלֹֽא־תִשְׁכַּ֣ח אֶת־אֲמָתֶ֔ךָ וְנָתַתָּ֥ה לַאֲמָתְךָ֖ זֶ֣רַע אֲנָשִׁ֑ים וּנְתַתִּ֤יו לַֽיהוָה֙ כָּל־יְמֵ֣י חַיָּ֔יו וּמוֹרָ֖ה לֹא־יַעֲלֶ֥ה עַל־רֹאשֽׁוֹ׃
Sie sprach ein Gelübde aus also: Herr Zebaot, wenn du siehst auf das Elend deiner Magd und mein gedenkest und nicht vergisst deiner Magd und gewährest deiner Magd einen männlichen Nachkommen, so will ich ihn weihen dem Herrn für all seine Lebenstage, ein Schermesser soll nicht kommen auf sein Haupt.
Mishnah Nazir
Samuel was a nazirite, according to the words of Rabbi Nehorai, as it says, “And no razor [morah] shall come upon his head” (I Samuel 1:11). It says with reference to Samson, “And [no] razor [morah]” (Judges 13:5) and it says with reference to Samuel, “And [no] razor [morah]”, just as “razor [morah]” in the case of Samson [teaches that he was] a nazirite, so “razor [morah]” in the case of Samuel [teaches that he was] a nazirite. Rabbi Yose says: but does not “morah” refer to [fear] of flesh and blood? Rabbi Nehorai said to him: But does it not also say, “And Samuel said; ‘How can I go? If Saul will hear it he will kill me’” (I Samuel 16:2) [which shows] that he was afraid of flesh and blood?
