Genesis 21
31 Ref Wherefore he called that place Beersheba; because there they sware both of them.
32 Ref 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.
33 Ref And Abraham planted a grove in Beersheba, and called there on the name of the LORD, the everlasting God.
