Judges 15:12-13

12And they said to him, "We have come down to bind you, that we may give you into the hands of the Philistines." And Samson said to them, "Swear to me that you will not attack me yourselves."

13They said to him, "No; we will only bind you and give you into their hands. We will surely not kill you." So they bound him with two new ropes and brought him up from the rock.
