[22] At that time Abimelech and Phicol the commander of his army said to Abraham, “God is with you in all that you do. [23] Now therefore swear to me here by God that you will not deal falsely with me or with my descendants or with my posterity, but as I have dealt kindly with you, so you will deal with me and with the land where you have sojourned.” [24] And Abraham said, “I will swear.” [25] When Abraham reproved Abimelech about a well of water that Abimelech’s servants had seized, [26] Abimelech said, “I do not know who has done this thing; you did not tell me, and I have not heard of it until today.” [27] So Abraham took sheep and oxen and gave them to Abimelech, and the two men made a covenant. [28] Abraham set seven ewe lambs of the flock apart. [29] And Abimelech said to Abraham, “What is the meaning of these seven ewe lambs that you have set apart?” [30] He said, “These seven ewe lambs you will take from my hand, that this may be a witness for me that I dug this well.” [31] Therefore that place was called Beersheba, because there both of them swore an oath. [32] So they made a covenant at Beersheba. Then Abimelech and Phicol the commander of his army rose up and returned to the land of the Philistines. [33] Abraham planted a tamarisk tree in Beersheba and called there on the name of the LORD, the Everlasting God. [34] And Abraham sojourned many days in the land of the Philistines. (ESV)
