Kabbalah su Genesi 26:11

"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).
