Commentary for Niddah 48:37

אמר לה

'Master', she said to him, 'what is your ruling where an abortion had the likeness of a serpent?' 'Its mother', he replied, 'is clean'. 'But', she retorted, 'was it not in your name that my mother-in-law told me that its mother was unclean?' 'And', he asked her, 'on what ground?' 'Since [she told him] its eye-ball is round like that of a human being'. As a result of her statements R. Joshua recollected his ruling and sent the following message to R. Gamaliel: 'Hanina gave his ruling on my authority'.<span class="x" onmousemove="('comment',' Lit., 'from my mouth'. ');">³²</span>
