Matthew Poole and continuators on Genesis 26:33

33 And he called it Sheba: therefore the name of the City is Beer-sheba unto this day.

This name had been given before either to this or a neighbouring place by Abraham, Gen. 21. 31. But was now buried in oblivion, as his wells were, and the wells being revived, he revives and renews the name, which proved now a lasting name, unto this day, as here follows, which is not added Gen. 21. 31. because then the name though given by Abraham was soon forgotten and neglected by others.

Marginal references: That is, an oath.; That is, the well of the oath.
