Judges 15:11-13

11Then three thousand men of Judah went down to the cleft of the rock of Etam, and said to Samson, “Do you not know that the Philistines rule over us? What is this you have done to us?” And he said to them, “As they did to me, so I have done to them.”

12But they said to him, “We have come down to arrest you, that we may deliver you into the hand of the Philistines.” Then Samson said to them, “Swear to me that you will not kill me yourselves.”

13So they spoke to him, saying, “No, but we will tie you securely and deliver you into their hand; but we will surely not kill you.” And they bound him with two new ropes and brought him up from the rock.
