Reference for Sotah 53:2
ור' יוחנן אמר ישא אדם בת דומה ואל ישא דומה שזו עומדת בחזקת כשרות וזו אינה עומדת בחזקת כשרות
R. Johanan, however, said: Let a man marry the daughter of a woman of ill-repute rather than a woman of ill-repute, since the former is presumably chaste whereas the latter is not. An objection was raised: One should marry a woman of ill-repute! — Raba said: Can you possibly think that [the meaning is that] he should marry [a woman of ill-repute who is such] at the outset? But the statement should take this form: 'If a man married [a woman of ill-repute']; and similarly [read] 'the daughter of a woman of ill-repute'.<span class="x" onmousemove="('comment',' [Since the Baraitha has to be amended in any case we might just as well amend 'a woman' into 'the daughter of a woman etc.'.] ');"><sup>2</sup></span>
