Komentaryo sa Genesis 20:5: Rashi, Chizkuni, Or HaChaim & Radak

גם 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).

והיא גם היא, the word היא is spelled with the letter י.

בתם לבבי ובנקיון כפי "I acted with innocence and integrity." Avimelech said these words in the event Sarah was married, but not to Abraham. He claimed that if that were so what would Abraham have gained by declaring that she was his sister? This exonerated him from the death penalty, i.e. בתם לבבי. When he added בנקיון כפי, he pleaded that he was not guilty of the death penalty for robbery either, though we have a ruling both in Sanhedrin 57 and in Maimonides (the chapter quoted above) that a Gentile who commits robbery is guilty of the death penalty. It does not matter that the robbery is an act of kidnapping as distinct from stealing. The Talmud deduces this when it discusses the status of a prisoner of war who is considered as the victim of robbery or stealing. Accordingly, from the moment Avimelech took Sarah against her will he became guilty of the death penalty. Avimelech claimed that he thought both Abraham and Sarah were pleased at his taking Sarah for a wife. After all, he was the king and it meant social climbing for them both.

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