The geological society of America says, " Karst geology played a major role in Jerusalem's selection by David for his capital," Bramnik says. It proved to be a wise decision. One of David's successors, King Hezekiah, watched as the warlike Assyrian horde, a group of vastly superior warriors toppled city after city in the region. Fearing that they'd soon come for Jerusalem, he too took advantage of the limestone bedrock and dug a 550 meter-long (1804 feet) tunnel that rerouted the spring's water inside the city's fortified walls."

The limestone the builders rejected becomes a stumbling block for Christians that they can not roll out the way. Maybe there was a sink hole in the tomb that Jesus fell down and then was flushed away by an underground stream. People couldn't see the hole in the dark?
The folk in Matthew 27v52 who looked like white ghosts were merely miners covered in white chalk and gypsum ?
