וְרֹאשָׁם֙ לֹ֣א יְגַלֵּ֔חוּ וּפֶ֖רַע לֹ֣א יְשַׁלֵּ֑חוּ כָּס֥וֹם יִכְסְמ֖וּ אֶת־רָאשֵׁיהֶֽם׃
Mereka tidak boleh mencukur gundul kepala mereka, dan tidak boleh membiarkan rambut mereka tumbuh panjang; mereka harus memangkas rambut kepala mereka dengan rapi.
Mishnah Nazir
All the substitutes for vows have the validity of vows. If one says, “I shall be [one]” he is a nazirite. “I shall be comely”, he is a nazirite. “A nazik”, “a naziah”, “a paziah”, he is a nazirite. [If one says,] “Behold I shall be like this one,” or “Behold I shall curl [my hair]” or “Behold, I shall tend [my hair]” or “Behold, I shall grow my hair long,” he is a nazirite. [If one says] “Behold, I shall [bring] birds [as offerings]” Rabbi Meir says he is a nazirite, but the sages say he is not a nazirite.
