Beersheba
    well of the oath, or well of seven, a well dug by Abraham, and
    so named because he and Abimelech here entered into a compact
    (Gen. 21:31). On re-opening it, Isaac gave it the same name
    (Gen. 26:31-33). It was a favourite place of abode of both of
    these patriarchs (21:33-22:1, 19; 26:33; 28:10). It is mentioned
    among the "cities" given to the tribe of Simeon (Josh. 19:2; 1
    Chr. 4:28). From Dan to Beersheba, a distance of about 144 miles
    (Judg. 20:1; 1 Chr. 21:2; 2 Sam. 24:2), became the usual way of
    designating the whole Promised Land, and passed into a proverb.
    After the return from the Captivity the phrase is narrowed into
    "from Beersheba unto the valley of Hinnom" (Neh. 11:30). The
    kingdom of the ten tribes extended from Beersheba to Mount
    Ephraim (2 Chr. 19:4). The name is not found in the New
    Testament. It is still called by the Arabs Bir es-Seba, i.e.,
    "well of the seven", where there are to the present day two
    principal wells and five smaller ones. It is nearly midway
    between the southern end of the Dead Sea and the Mediterranean.
