Genesis 21:31

²⁹And Abimelech said to Abraham, What are these seven ewe lambs which thou hast set alone?

³⁰And Abraham said, Thou shalt receive the seven ewe lambs of me, that they may be for me as a witness, that I dug this well.

— Genesis 21:31 —

³²And they made a covenant at the well of the oath. And there rose up Abimelech, Ahuzzath his friend, and Phicol the commander-in-chief of his army, and they returned to the land of the Philistines.

³³And Abraham planted a field at the well of the oath, and called there on the name of the Lord, the everlasting God.
