'Cleft of the Rock' in the Bible

And {he gave them a thorough beating}, and he went down and stayed in the cleft of the rock of Etam.

Then three thousand men from Judah went down to the cleft of the rock of Etam, and they said to Samson, "Do you not know that the Philistines [are] ruling over us? What [is] this [that] you have done to us?" And he said to them, "Just as they did to me, so I have done to them."
