Genesis 26:31-33

21st Century King James Version

³¹ And they rose up early in the morning and swore one to another; and Isaac sent them away, and they departed from him in peace.

³² And it came to pass the same day, that Isaac’s servants came and told him concerning the well which they had dug, and said unto him, “We have found water.”

³³ And he called it Shebah [that is, An oath]; therefore the name of the city is Beersheba [that is, The well of the oath] unto this day.
