Genesis 21:30-32 Darby Translation (DARBY)
30 And he said, That thou take the seven ewe-lambs of my hand, that they may be a witness to me that I have dug this well.
31 Therefore he called that place Beer-sheba, because there they had sworn, both of them.
32 And they made a covenant at Beer-sheba. And Abimelech rose up, and Phichol the captain of his host, and returned into the land of the Philistines.
