Parallel
Genesis 21:31
Swete's Septuagint · Berean Standard Bible
διὰ τοῦτο ἐπωνόμασεν τὸ ὄνομα τοῦ τόπου ἐκείνου Φρέαρ ὁρκισμοῦ, ὅτι ἐκεῖ ὤμοσαν ἀμφότεροι.
So that place was called Beersheba (note: Beersheba means well of seven or well of the oath.), because it was there that the two of them swore an oath.
