Genesis
Chapters 21:30-34
English Revised Version
30And he said, These seven ewe lambs shalt thou take of my hand, that it may be a witness unto me, that I have digged this well.
31Wherefore he called that place Beer-sheba; because there they sware both of them.
32So they made a covenant at Beer-sheba: and Abimelech rose up, and Phicol the captain of his host, and they returned into the land of the Philistines.
33And Abraham planted a tamarisk tree in Beer-sheba, and called there on the name of the LORD, the Everlasting God.
34And Abraham sojourned in the land of the Philistines many days.
