Genesis 21:31-33

Revised Standard Version

³¹ Therefore that place was called Beer-sheba;^[a] because there both of them swore an oath. ³² So they made a covenant at Beer-sheba. Then Abim′elech and Phicol the commander of his army rose up and returned to the land of the Philistines. ³³ Abraham planted a tamarisk tree in Beer-sheba, and called there on the name of the Lord, the Everlasting God.
