וְהָיָה֩ בַיּ֨וֹם הַשְּׁבִיעִ֜י יְגַלַּ֣ח אֶת־כָּל־שְׂעָר֗וֹ אֶת־רֹאשׁ֤וֹ וְאֶת־זְקָנוֹ֙ וְאֵת֙ גַּבֹּ֣ת עֵינָ֔יו וְאֶת־כָּל־שְׂעָר֖וֹ יְגַלֵּ֑חַ וְכִבֶּ֣ס אֶת־בְּגָדָ֗יו וְרָחַ֧ץ אֶת־בְּשָׂר֛וֹ בַּמַּ֖יִם וְטָהֵֽר׃
And it shall be on the seventh day, that he shall shave all his hair off his head and his beard and his eyebrows, even all his hair he shall shave off; and he shall wash his clothes, and he shall bathe his flesh in water, and he shall be clean.
Mishnah Negaim
What is [the posture] of examining negaim? A man is inspected in the posture of one that hoes or one that gathers olives. And a woman [is inspected in the posture] of one who is arranging dough and one who nurses her child, and one that weaves at an upright loom if the nega was in the right armpit. Rabbi Judah says: also in the posture of one that spins flax if it was within the left armpit. Just as [is the posture] for examining for the nega, so too [is the posture] for shaving hair.
Mishnah Negaim
On the seventh day he shaves off his hair a second time in the manner of the first shaving, he washes his garments and immerses himself. He is clean in so far as not to convey uncleanness as a sheretz, but he was still like a tevul yom. He may eat second tithe. After sunset he may eat terumah. After he had brought his offering of atonement, he may also eat sacred things. Thus there are three grades in the purification of a metzora and three grades in the purification of a woman after child birth.
