כִּֽי־יִהְיֶ֤ה בְךָ֙ אִ֔ישׁ אֲשֶׁ֛ר לֹא־יִהְיֶ֥ה טָה֖וֹר מִקְּרֵה־לָ֑יְלָה וְיָצָא֙ אֶל־מִח֣וּץ לַֽמַּחֲנֶ֔ה לֹ֥א יָבֹ֖א אֶל־תּ֥וֹךְ הַֽמַּחֲנֶֽה׃
Se houver entre ti algum homem que não esteja puro por causa de uma emissão noturna, sairá para fora do acampamento; ele não entrará no meio do acampamento.
Jerusalem Talmud Peah
Where is a warning about calumny159? (Deut. 23:10) “Keep yourself from every evil word!” Rebbi La said that Rebbi Ismaël stated (Lev.19:10): “Do not walk around as slanderer among your people,” that is slandering, calumny. Rebbi Nehemiah stated that you should not be like a trader who carries things from one person to another and vice versa.
