Genesis 21:30-32

King James Version

³⁰ And he said, For these seven ewe lambs shalt thou take of my hand, that they may be a witness unto me, that I have digged this well.

³¹ Wherefore he called that place Beersheba; because there they sware both of them.

³² Thus they made a covenant at Beersheba: then Abimelech rose up, and Phichol the chief captain of his host, and they returned into the land of the Philistines.
