Genesis 21:31

Wherefore he called that place Beersheba; because there they sware both of them.

Therefore he called that place Beersheba, because they both swore there.

Wherefore he called that place Beer-sheba. Because there they sware both of them.

therefore hath he called that place `Beer-Sheba,' for there have both of them sworn.

So that place was called Beersheba, because it was there that the two of them swore an oath.
