Judges 15:9-13

Then the [army of the] Philistines came up and camped in [the tribal territory of] Judah, and overran Lehi (Jawbone). The men of Judah said, “Why have you come up against us?” And they answered, “We have come up to bind Samson, in order to do to him as he has done to us.” Then three thousand men of Judah went down to the cleft of the rock of Etam and said to Samson, “Have you not known that the Philistines are rulers over us? What is this that you have done to us?” He said to them, “As they did to me, so I have done to them.” They said to him, “We have come down to bind you, so that we may hand you over to the Philistines.” And Samson said to them, “Swear to me that you will not kill me.” So they said to him, “No, we will [only] bind you securely and place you into their hands; but we certainly will not kill you.” So they bound him with two new ropes and brought him up from the rock [of Etam].
