Rashi on Exodus 32:32/רש"י על שמות ל״ב:ל״ב

1ועתה אם תשא חטאתם YET NOW, IF THOU WILT FORGIVE THEIR SIN — well and good: then I do not suggest to You, “Blot me out [of Thy book], ואם אין מחני BUT IF NOT, BLOT ME OUT.” This is an elliptical sentence, the words “Well and good” being omitted; of such there are many in Scripture.

2מספרך OF THY BOOK — of the entire book of the Torah; that people should not say about me that I was not worthy enough to pray effectively for them.
