Rashi on Genesis 20:5/רש"י על בראשית כ׳:ה׳

1גם הוא ALSO SHE HERSELF — The word “also” presupposes that others also said the same: it serves to include her servants, cameldrivers and assdrivers — all these I asked and they told me, “He is her brother” (Genesis Rabbah 52:6).

2בתם לבבי IN THE INTEGRITY OF MY HEART —I did not intend to sin.

3ובנקיון כפי AND IN THE INNOCENCY OF MY HANDS —I am innocent of this sin because I have not touched her.
