Leviticus 13:21

וְאִ֣ם׀ יִרְאֶ֣נָּה הַכֹּהֵ֗ן וְהִנֵּ֤ה אֵֽין־בָּהּ֙ שֵׂעָ֣ר לָבָ֔ן וּשְׁפָלָ֥ה אֵינֶ֛נָּה מִן־הָע֖וֹר וְהִ֣יא כֵהָ֑ה וְהִסְגִּיר֥וֹ הַכֹּהֵ֖ן שִׁבְעַ֥ת יָמִֽים׃

ἐὰν δὲ ἴδῃ ὁ ἱερεύς, καὶ ἰδοὺ οὐκ ἔστιν ἐν αὐτῷ θρὶξ λευκή, καὶ ταπεινὸν μὴ ᾖ ἀπὸ τοῦ δέρματος τοῦ χρωτός, καὶ αὐτὴ ἦ ἀμαυρά, ἀφοριεῖ αὐτὸν ὁ ἱερεὺς ἑπτὰ ἡμέρας.

Y si el sacerdote la considerare, y no pareciere en ella pelo blanco, ni estuviere más baja que la piel, sino oscura, entonces el sacerdote lo encerrará por siete días:

But when the priest examines it, if there is no white hair in it, and it is not beneath the skin and has faded, the priest shall isolate him for seven days.
