כִּֽי־יִהְיֶ֤ה בְךָ֙ אִ֔ישׁ אֲשֶׁ֛ר לֹא־יִהְיֶ֥ה טָה֖וֹר מִקְּרֵה־לָ֑יְלָה וְיָצָא֙ אֶל־מִח֣וּץ לַֽמַּחֲנֶ֔ה לֹ֥א יָבֹ֖א אֶל־תּ֥וֹךְ הַֽמַּחֲנֶֽה׃
S’il se trouve dans tes rangs un homme qui ne soit pas pur, par suite d’un accident nocturne, il se retirera du camp, où il ne rentrera pas.
Pesachim
R. Papa said: "A circumlocution of nine letters is found in the Scripture; for it is said (Deu. 23:11) If there be among thee, any man that is not clean." Rabina said : "Ten letters [is the circumlocution]; for in the same text there is an an extra letter, Vav." R. Acha b. Jacob said: "Sixteen extra letters are used [in order to avoid an unfit word], as it is said (I Sam. 20:26) For he thought something hath befallen him, he is not clean, because he has not yet purified himself [in order to avoid the word impure]."
