Le Lévitique 13:39 Références de la Michna : Mishnah Negaim

וְרָאָ֣ה הַכֹּהֵ֗ן וְהִנֵּ֧ה בְעוֹר־בְּשָׂרָ֛ם בֶּהָרֹ֖ת כֵּה֣וֹת לְבָנֹ֑ת בֹּ֥הַק ה֛וּא פָּרַ֥ח בָּע֖וֹר טָה֥וֹר הֽוּא׃ (ס)

et que le pontife, examinant, constate sur leur peau des taches d’un blanc obscur, c’est un exanthème qui s’est développé sur la peau: Il est pur.

Mishnah Negaim

Rabbi Shimon said: when is this the case? When the quick flesh was exactly the size of a lentil. But if it was larger than a lentil, the excess is a sign of spreading of the inner one, and the outer one is unclean. If there was white scurf less that the size of a lentil, it is a sign of the spreading of the inner bright spot but it is not a sign of spreading of the outer one.
