Judges 15:12-13

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.
