Genesis 26:33

29 do not evil with us, as we have not touched thee, and as we have only done good with thee, and send thee away in peace; thou [art] now blessed of Jehovah.`

30 And he maketh for them a banquet, and they eat and drink,

31 and rise early in the morning, and swear one to another, and Isaac sendeth them away, and they go from him in peace.

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.
