Genesis 21:31-33

Webster(i) 31 Wherefore he called that place Beer-sheba: because there they swore both of them. 32 Thus they made a covenant at Beer-sheba: Then Abimelech arose, and Phichol the chief captain of his host, and they returned into the land of the Philistines. 33 And Abraham planted a grove in Beer-sheba, and called there on the name of the LORD, the everlasting God.
