Midrash su Genesi 13:7

(Exodus 15:15) "Then the chiefs of Edom were confounded": If you say because they (thought) they were coming to inherit their land, is it not written (Devarim 2:5) "… for I will not give you of their (Edom's) land"? What, then, is the intent of "Then the chiefs of Edom were confounded"? Because of worry (over contention.) They said: Now they are coming to stir up strife because of our father's hatred of their father, viz. (Genesis 27:41) "And Esav hated Jacob." (Exodus, Ibid.) "the mighty ones of Moav" (were confounded. Why so?) If you say because they (thought) they were coming to inherit their land, is it not written (Devarim 2:9) "Do not antagonize Moav, etc." and (Ibid. 19) "When you come opposite the children of Ammon, do not antagonize them, etc."? What, then, is the intent of "the mighty ones of Moav (were seized with trembling")? Because of worry (over contention.) They said: Now they are coming to rekindle the strife between our father and theirs, viz.(Genesis 13:7) "And there was strife between the herdsmen of Avram's cattle and those of Lot's, etc."

What is written above on the matter (in Gen. 14:14)?⁷²Tanh., Gen. 3:13. WHEN ABRAM HEARD THAT HIS BROTHER HAD BEEN CAPTURED. Was he Lot's brother? Look, however, at the humility of our father Abraham after all the strife they had had with him, [as stated (in Gen. 13:7): NOW THERE WAS QUARRELING BETWEEN THE HERDSMEN OF ABRAM'S CATTLE AND THE HERDSMEN OF LOT'S CATTLE.] Our father Abraham did not remember the strife but called him his brother, as stated (in Gen. 13:8): FOR WE ARE BROTHERS.

(Devarim 25:11) "If men strive together": Peace does not proceed from strife, as it is written (Bereshith 13:7) "And there was a quarrel between the herdsmen of Avram's cattle and the herdsmen of Lot's cattle." What is it that caused Lot to part from Avram? A quarrel. And thus is it written (Ibid. 1) "If there be a quarrel among men, etc." What caused this one to receive stripes (viz. Ibid. 2)? A quarrel.
