Genesis 21:30–33

30 He said, “You shall take these seven ewe lambs from my hand so that it may be a awitness to me, that I dug this well.”

31 Therefore he called that place aBeersheba, because there the two of them took an oath.

32 So they made a covenant at Beersheba; and Abimelech and Phicol, the commander of his army, arose and returned to the land of the Philistines.

33 Abraham planted a tamarisk tree at Beersheba, and there ahe called on the name of the Lord, the bEverlasting God.
