Genesis 21:22-34

22Now it came about at that same time that Abimelech—with Phicol the commander of his army---said to Abraham, “God is with you in all that you do.

23So now, make a pledge to me here, by God, that you will not violate your word with me or with my descendants or with my offspring. As I have shown loyalty to you, show the same to me, and to the land in which you have lived as an outsider.”

24Abraham said, “I make a pledge.”

25Now Abraham had rebuked Abimelech because of the well of water that Abimelech’s servants had seized.

26So Abimelech said, “I don’t know who did this thing. Nor did you tell me, nor did I hear about it until today.”

27Then Abraham took a flock of sheep and cattle and gave them to Abimelech, and the two of them made a covenant.

28Abraham set seven young ewe-lambs apart from the flock of sheep by themselves.

29Abimelech said to Abraham, “What do these seven ewe-lambs that you’ve set by themselves mean?”

30He said, “You are to accept the seven ewe-lambs from my hand, so that they may be a witness for me that I dug this well.”

31That is why that place is named Beer-sheba, because there both of them made a pledge,

32and they made a covenant in Beer-sheba. Then Abimelech got up, with Phicol the commander of his army, and they returned to the land of the Philistines.

33Then he planted a tamarisk tree in Beer-sheba and called there on the Name of Adonai, the Everlasting God.

34He lived as an outsider in the land of the Philistines for many days.
