Genesis 28:9

Esau went to Ismael, and took Maeleth the daughter of Ismael, the son of Abraam, the sister of Nabeoth, a wife in addition to his [other] wives.

Then went Esau unto Ishmael, and took unto the wives which he had Mahalath the daughter of Ishmael Abraham’s son, the sister of Nebajoth, to be his wife.

So Esau went to Ishmael, and took, in addition to the wives that he had, Mahalath the daughter of Ishmael, Abraham’s son, the sister of Nebaioth, to be his wife.
