(Jdg 15:9-13) Then the Philistines went up--to the high land of Judah. and spread themselves in Lehi--now El-Lekieh, abounding with limestone cliffs; the sides of which are perforated with caves. The object of the Philistines in this expedition was to apprehend Samson, in revenge for the great slaughter he had committed on their people.
