Judges 15:12-13

12They said to him, “We’ve come to tie you up and hand you over to the Philistines.” Samson said, “Swear to me that you won’t kill me yourselves.” 13“Agreed,” they answered. “We will only tie you up and hand you over to them. We will not kill you.” So they bound him with two new ropes and led him up from the rock.
