Genesis 26:30-35

26:30 So Isaac held a feast for them and they celebrated. 26:31 Early in the morning the men made a treaty with each other. Isaac sent them off; they separated on good terms.

26:32 That day Isaac’s servants came and told him about the well they had dug. “We’ve found water,” they reported. 26:33 So he named it Shibah; that is why the name of the city has been Beer Sheba to this day.

26:34 When Esau was forty years old, he married Judith the daughter of Beeri the Hittite, as well as Basemath the daughter of Elon the Hittite. 26:35 They caused Isaac and Rebekah great anxiety.
