Reference for Yoma 80:5
טעמא דאל תתנו מקום לצדוקים לרדות הא לאו הכי מהדרינן ליה והא אמרת הגרלה מעכבא וכיון דקבעתיה שמאל היכי מהדרינן ליה
The disciples of R'Akiba asked him: If it [the lot 'for the Lord'] came up in the left han may he turn it to the right? He replied: Do not give all occasion for the Sadducees to rebel!<span class="x" onmousemove="('comment',' The substitution of Sadducees for 'Minim' (Judeo-Christian heretics) is undoubtedly due to the censors' dislike of any word that may appear as even an implied attack on the Church. The heretics will claim this manipulation an 'additional proof' of the Pharisees' doing with the law whatever pleased them. Thus they would be helped to rebel, arguing at once in favour of their heresy and against the Pharisees.');"><sup>6</sup></span>
