Genesis 26:26-35

Abimelech came from Gerar to see Isaac. He brought with him Ahuzzath, who advised him, and Phicol, the commander of his army. Isaac asked them, “Why have you come to see me? You were my enemy and forced me to leave your country.” They answered, “Now we know that the LORD is with you. Let us swear an oath to each other. Let us make an agreement with you that since we did not hurt you, you will not hurt us. We were good to you and sent you away in peace. Now the LORD has blessed you.” So Isaac prepared food for them, and they all ate and drank. Early the next morning the men swore an oath to each other. Then Isaac sent them away, and they left in peace. That day Isaac’s servants came and told him about the well they had dug, saying, “We found water in that well.” So Isaac named it Shibah and that city is called Beersheba even now. When Esau was forty years old, he married two Hittite women—Judith daughter of Beeri and Basemath daughter of Elon. These women brought much sorrow to Isaac and Rebekah.
