Reference for Shabbat 290:2
איבעיא להו עד מפי עד לעדות בכור מהו רב אמי אסיר ורב אסי שרי
— R. Ammi forbids [the admission of his testimony]; while R. Assi permits it. Said R. Ammi to R. Ashi, But the School of Menasseh taught: A witness testifying what he heard from another witness is valid in testimony concerning a woman alone? — Say: Only in testimony for which a woman is valid.<span class="x" onmousemove="('comment',' A woman is a valid witness only in certain matters, which includes a firstling's blemish, and in these hearsay too is admissible. ');"><sup>3</sup></span> R. Yemar recognized as fit a witness [testifying] from the mouth of another witness in respect to a firstling, [whereupon] Meremar called him 'Yemar who permits firstlings.'<span class="x" onmousemove="('comment',' Said in a critical spirit.
