Dear Rabbi Kornfeld,
Could you please explain to me why Rashi reverses the original order, of the discussion in Sanhedrin 108a, re. B"DOROSOV Brayshis ch. 6 verse 9.
(gemorra order LIGNYE ------SHVACH Rashi's order SHVACH--------LIGNYE)
Best Wishes Stuart
The Gemara cites Rebbi Yochanan (who explained l'Genai) before Reish Lakish (who explained "l'Shevach") because he is older, and he is always cited first. Rashi does not mention names, so he begins with Shevach, so as not to begin with Genai.
