The Agreement between Isaac and Abimelech (GEN 26:26-33)

[26:26] Abimelech came from Gerar with Ahuzzath his adviser and Phicol the commander of his army to see Isaac.

[26:27] So Isaac asked, “Why have you now come to see me, when you were so unfriendly to me before and made me leave your country?”

[26:28] They answered, “Now we know that the Lord is with you, and we think that there should be a solemn agreement between us. We want you to promise

[26:29] that you will not harm us, just as we did not harm you. We were kind to you and let you go peacefully. Now it is clear that the Lord has blessed you.”

[26:30] Isaac prepared a feast for them, and they ate and drank.

[26:31] Early next morning each man made his promise and sealed it with a vow. Isaac said good-bye to them, and they parted as friends.

[26:32] On that day Isaac's servants came and told him about the well which they had dug. They said, “We have found water.”

[26:33] He named the well “Vow.” That is how the city of Beersheba got its name.
