Genesis 21:30-32

New Century Version

³⁰ Abraham answered, “Accept these lambs from me to prove that you believe I dug this well.”

³¹ So that place was called Beersheba^[a] because they made a promise to each other there.

³² After Abraham and Abimelech made the agreement at Beersheba, Abimelech and Phicol, the commander of his army, went back to the land of the Philistines.
