An Israeli archeologist may have bolstered the "Bible as history" argument by discovering the water tunnel that David used to conquer Jerusalem.
In the second Book of Samuel, David orders the capture of the walled city by entering it through the water shaft. Shukron's excavation uncovered a narrow shaft where spring water flowed into a carved pool, thought to be where city inhabitants would gather to draw water. Excess water would have flowed out of the walled city through another section of the shaft Shukron said he discovered — where he believes the city was penetrated.
