Easton's Bible Dictionary (1897)
I.e., “the well of him that liveth and seeth me,” or, as some render it, “the well of the vision of life”, the well where the Lord met with Hagar (Gen. 16:7-14). Isaac dwelt beside this well (24:62; 25:11). It has been identified with ‘Ain Muweileh, or Moilahhi, south-west of Beersheba, and about 12 miles W. from Kadesh-barnea.
