Then Joshua built an altar to Yahweh, the God of Israel, in Mount Ebal,
"Ebal and Gerizim are only a mile and a half apart, and only 500 yards apart at their base."[32]  Gerizim  Isaiah 2,895 feet above sea level; Ebal  Isaiah 3,077 feet above sea level; and they rise about 1,300 feet and 1,500 feet respectively above the surrounding valley.[33]  The two great bays lying near the base of each mountain provide one of the grandest amphitheaters on earth!
