Judges 15:12-13

12They said to him, “We’ve come to tie you up and hand you over to the Philistines.” Then Samson told them, “Swear to me that you yourselves won’t kill me.”

13“No,” they said, “we won’t kill you, but we will tie you up securely and hand you over to them.” So they tied him up with two new ropes and led him away from the rock.
