Genesis 26:26-33 - Covenant With Abimelech
26 Abimelech came from Gerar with Ahuzzath, his friend (companion), and Phicol, the commander of his army, to see Isaac. 27 Isaac asked: Why have you now come to see me? You were so unfriendly to me before and made me leave your country.
28 They answered: Now we know that Jehovah is with you. We think that there should be a solemn agreement between us. We want you to promise 29 that you will not harm us. We did not harm you. We were kind to you and let you go peacefully. Now it is clear that Jehovah has blessed you.
30 Isaac prepared a feast for them, and they ate and drank. 31 Early the next morning each man made his promise and sealed it with a vow. Isaac said good-bye to them. They parted as friends.
32 That day Isaac's servants told him about the well they dug. They said: We have found water. 33 Isaac named the well Shibah. The town is still called Beer-sheba.
