Genesis 21:25-32

25But Abraham lodged a complaint against Abimelech concerning a well that Abimelech’s servants had seized.

26“I do not know who has done this thing,” Abimelech replied. “Moreover, you did not tell me. I did not hear about it until today.”

27Abraham took some sheep and cattle and gave them to Abimelech. The two of them made a treaty.

28Then Abraham set seven ewe lambs apart from the flock by themselves.

29Abimelech asked Abraham, “What is the meaning of these seven ewe lambs that you have set apart?”

30He replied, “You must take these seven ewe lambs from my hand as legal proof that I dug this well.”

31That is why he named that place Beer Sheba, because the two of them swore an oath there.

32So they made a treaty at Beer Sheba. Then Abimelech and Phicol, the commander of his army, returned to the land of the Philistines.
