Genesis 26:34 YLT

³²  And it cometh to pass during that day that Isaac's servants come and declare to him concerning the circumstances of the well which they have digged, and say to him, 'We have found water;'

³³  and he calleth it Shebah, 'oath,' therefore the name of the city 'is' Beer-Sheba, 'well of the oath,' unto this day.

³⁴  And Esau is a son of forty years, and he taketh a wife, Judith, daughter of Beeri the Hittite, and Bashemath, daughter of Elon the Hittite,

³⁵  and they are a bitterness of spirit to Isaac and to Rebekah.
