Judges 15:11-13

11Then 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.”

12They 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.”

13So 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].
