וְכֹֽה־תַעֲשֶׂ֤ה לָהֶם֙ לְטַֽהֲרָ֔ם הַזֵּ֥ה עֲלֵיהֶ֖ם מֵ֣י חַטָּ֑את וְהֶעֱבִ֤ירוּ תַ֙עַר֙ עַל־כָּל־בְּשָׂרָ֔ם וְכִבְּס֥וּ בִגְדֵיהֶ֖ם וְהִטֶּהָֽרוּ׃
At ganito ang gagawin mo sa kanila upang linisin sila: wisikan mo sila ng tubig ng paglilinis, at padaanin nila ang labaha sa buong katawan nila, at labhan nila ang kanilang mga kasuotan, at linisin nila ang kanilang sarili.
Mishnah Negaim
There are three who must shave their hair, and their shaving of it is a commandment: the nazirite, the metzora, and the Levites. If any of these cut their hair but not with a razor, or if they left even two remaining hairs, their act is of no validity.
