Jacob’s Well means in the bible: John 4:42 – The conversation between our Lord and Samaria. A well with the same name is still present, at 75 feet, in the vicinity of Nablus. It’s close to Nablus, an ancient Shechem. Shechem was Jacob’s residence for many years following his return from Laban. Gen. 33.18; 37.12.
