וְרָאָ֧ה הַכֹּהֵ֛ן אֶת־הַבָּשָׂ֥ר הַחַ֖י וְטִמְּא֑וֹ הַבָּשָׂ֥ר הַחַ֛י טָמֵ֥א ה֖וּא צָרַ֥עַת הֽוּא׃
And the priest shall look on the raw flesh, and pronounce him unclean; the raw flesh is unclean: it is leprosy.
Targum Jonathan on Leviticus
And the priest shall observe the live flesh, and make him to be unclean; on account of the live flesh in him he is unclean; it is leprosy.
