When human beings think that they have found mistakes in the Bible, they are eventually judged by their own words. Beneath old Jerusalem lies a complex, ancient water supply system. However, archaeologists have long considered it to be poorly designed. Worse, they said that the biblical account of David's capture of Jerusalem was in error since it mentioned water tunnels that didn't exist in his time. Now these archaeological and biblical critics have been proven wrong on both counts.
A detailed study of the tunnels beneath old Jerusalem reveals a cleverly designed and sophisticated dual water supply system that served the city. Nearly 3,000 years ago, ancient engineers modified a natural network of channels and tunnels under old Jerusalem to create the unique system. New tunnels were used to link existing natural tunnels so that an ambitious engineering project was completed with the least amount of work.
Research also shows that there are two openings to the system outside the walls of Jerusalem. It was one of these natural openings that David used to enter and conquer Jerusalem. Since we now know that they were natural and not built after David's time, no one can claim that the Bible's account is untrue.
Skeptics have claimed they have discovered many errors of historical or scientific fact in the Bible. Every time more facts have been learned, the Bible has been vindicated.
