Kabbalah su Genesi 20:78

Come and behold, it is written, "Because I thought, 'Surely the fear of Elohim is not in this place'" (Beresheet 20:11). According to Rabbi Abba, this is the reason why he said, "She is my sister." He wanted to cleave to the Shechinah, as it is written, "Say to wisdom, you are my sister."Why? Because they had no faith in them, for if they had faith, he would not have needed that. He therefore said, "Because I thought, 'Surely the fear of Elohim is not is not in this place." The fear of Elohim is Faith.

"And Abimelech charged all his people, saying, 'He that touches this man or his wife shall surely be put to death'" (Beresheet 26:11). Come and behold, how long had the Holy One, blessed be He, refrained from avenging the wicked, for as a result of the good Abimelech did with the first Patriarchs, the children of Yisrael did not rule over the Philistines until generations later. Abimelech did well to act properly toward Isaac, as he said (to Abraham), "Behold, my land is before you, dwell where it pleases you" (Beresheet 20:15).
