Bereshit Rabbah

“Esau saw that the daughters of Canaan were objectionable in the eyes of Isaac his father” (Genesis 28:8).
“Esau went to Ishmael, and took Maḥalat the daughter of Ishmael, son of Abraham, sister of Nevayot, in addition to his wives, as his wife” (Genesis 28:9).

“Esau saw that the daughters of Canaan26Ḥet was considered a Canaanite.…Esau went to Ishmael” – Rabbi Yehoshua ben Levi said: He gave consideration to converting.27The reference is to repenting. “Maḥalat” – as the Holy One blessed be He forgave [mahal] him for his iniquities. “Basmat” (Genesis 36:3) – as his mind was now satisfied [nitbasma]. Rabbi Elazar said: Had he divorced the first ones, it would have been correct, but, “in addition to his wives” – pain upon pain. Another matter, thorn upon thorn – it was an addition to a full house.
“Jacob departed from Beersheba, and went to Haran” (Genesis 28:10).
Rabbi Yudan said in the name of Rabbi Aivu: “In the transgression of the lips is an evil snare, but the righteous emerges from trouble” (Proverbs 12:13). “In the transgression of the lips is an evil snare” – due to the rebellion that Esau and Ishmael rebelled against the Holy One blessed be He, and angered him, and, likewise, his wives angered Him, they encountered a snare. “But the righteous emerges [vayetze] from trouble” – this is Jacob, “Jacob departed from Beersheba, and went to Haran.”
