וְשָׁכַ֨ב אִ֣ישׁ אֹתָהּ֮ שִׁכְבַת־זֶרַע֒ וְנֶעְלַם֙ מֵעֵינֵ֣י אִישָׁ֔הּ וְנִסְתְּרָ֖ה וְהִ֣יא נִטְמָ֑אָה וְעֵד֙ אֵ֣ין בָּ֔הּ וְהִ֖וא לֹ֥א נִתְפָּֽשָׂה׃
and a man lie with her carnally, and it be hid from the eyes of her husband, she being defiled secretly, and there be no witness against her, neither she be taken in the act;
Mishnah Eduyot
Rabbi Yose ben Yoezer, a man of Zereda, testified concerning the ayal-locust, that it is pure; And concerning liquid in the slaughter-house (of the Temple), that it is pure; And that one who touches a corpse is impure. And they called him “Yose the permitter”.
