Charles Ellicott Commentary Judges 15:13

"And they spake unto him, saying, No; but we will bind thee fast, and deliver thee into their hand: but surely we will not kill thee. And they bound him with two new ropes, and brought him up from the rock." — Judges 15:13 (ASV)

Brought him up from the rock. —Again the details are uncertain. Was Samson’s cave down the steep side of a cliff? Such caves are common in Palestine, and such a situation would explain these expressions. (See Josephus, Antiquities of the Jews, Book 14, Chapter 15, section 5, where he says that the brigands’ caves were inaccessible if defended by a few defenders, either from below or from above, and that Herod could only attack the robbers by letting down soldiers in chests from the top of the precipices.)
