Kabbalah su Genesi 26:16

Rabbi Yehuda said, Woe to the wicked, whose generosity is not complete. Come and behold, Efron first said, "my lord, hear me, the field I give you, and the cave that is in it" (Beresheet 23:11). Later he said, "four hundred shekels" (Ibid. 14), and then, "and Abraham weighed to Efron current money with the merchant" (Ibid. 16). Here too, it is written at first "Behold, my land is before you,". Then he said (to Isaac), "Go from us; for you are much mightier than we" (Beresheet 26:16). Rabbi Elazar said to him, This is the benevolence Abimelech had for Isaac. He took nothing from him and sent him away with his money and possessions. Then, he went after him to make a covenant with him.
