Genesis 21:22–33

²²At that time Abimelech and Phicol the commander of his army said to Abraham, “God is with you in all that you do; ²³now therefore swear to me here by God that you will not deal falsely with me or with my offspring or with my posterity, but as I have dealt loyally with you, you will deal with me and with the land where you have sojourned.” ²⁴And Abraham said, “I will swear.”

²⁵When Abraham complained to Abimelech about a well of water which Abimelech’s servants had seized, ²⁶Abimelech said, “I do not know who has done this thing; you did not tell me, and I have not heard of it until today.” ²⁷So Abraham took sheep and oxen and gave them to Abimelech, and the two men made a covenant. ²⁸Abraham set seven ewe lambs of the flock apart. ²⁹And Abimelech said to Abraham, “What is the meaning of these seven ewe lambs which you have set apart?” ³⁰He said, “These seven ewe lambs you will take from my hand, that you may be a witness for me that I dug this well.” ³¹Therefore that place was called Beer-sheba;^j because there both of them swore an oath. ³²So they made a covenant at Beer-sheba. Then Abimelech and Phicol the commander of his army rose up and returned to the land of the Philistines. ³³Abraham planted a tamarisk tree in Beer-sheba, and called there on the name of the Lord, the Everlasting God.
