Genesis 26:31-33

New Living Translation

³¹ Early the next morning, they each took a solemn oath not to interfere with each other. Then Isaac sent them home again, and they left him in peace.

³² That very day Isaac’s servants came and told him about a new well they had dug. “We’ve found water!” they exclaimed. ³³ So Isaac named the well Shibah (which means “oath”). And to this day the town that grew up there is called Beersheba (which means “well of the oath”).
