Leviticus 13:8

וְרָאָה הַכֹּהֵן אֹתוֹ בַּיּוֹם הַשְּׁבִיעִי שֵׁנִית וְהִנֵּה כֵּהָה הַנֶּגַע וְלֹא־פָשָׂה הַנֶּגַע בָּעוֹר וְטִהֲרוֹ הַכֹּהֵן מִסְפַּחַת הִיא וְכִבֶּס בְּגָדָיו וְטָהֵֽר

And the priest shall look on him again the seventh day; and, behold, if the plague be dim, and the plague be not spread in the skin, then the priest shall pronounce him clean: it is a scab; and he shall wash his clothes, and be clean.

וְאִם־פָּשֹׂה תִפְשֶׂה הַמִּסְפַּחַת בָּעוֹר אַחֲרֵי הֵרָאֹתוֹ אֶל־הַכֹּהֵן לְטָהֳרָתוֹ וְנִרְאָה שֵׁנִית אֶל־הַכֹּהֵֽן

But if the scab spread abroad in the skin, after that he hath shown himself to the priest for his cleansing, he shall show himself to the priest again.

נֶגַע צָרַעַת כִּי תִהְיֶה בְּאָדָם וְהוּבָא אֶל־הַכֹּהֵֽן

When the plague of leprosy is in a man, then he shall be brought unto the priest.

וְרָאָה הַכֹּהֵן וְהִנֵּה שְׂאֵת־לְבָנָה בָּעוֹר וְהִיא הָפְכָה שֵׂעָר לָבָן וּמִֽחְיַת בָּשָׂר חַי בַּשְׂאֵֽת

And the priest shall look, and, behold, if there be a white rising in the skin, and it have turned the hair white, and there be quick raw flesh in the rising,
