The small "chaf"

"And Avraham came to eulogize Sarah and to cry over her"; The word "to cry over her" is "ViLivkosa". The Torah spells it with a small "Chaf". What is the significance of this small letter?

The Satan has many ways to get us to sin. He tries at times to stop one from doing a Mitzvah beforehand. If he doesn't succeed, he will try to make us regret that we did the Mitzvah, therefore lessening our reward. Avraham did a great Mitzvah by offering his son a Korbon by the Akeidah. It was because of the news of the Akeidah where Yitzchok was almost killed, that caused Sarah to die. The Satan wanted Avraham to regret the Akeidah because it killed his wife. Avraham did not want to show this regret. He therefore minimized his weeping by the funeral of Srah to show that he did not regret the Akeidah. That is why it says a small "Chaf' - because he minimized his weeping.
