Judges 15:12-13

12The men of Judah said to him, ‘We have come to tie you up as our prisoner. We must let the Philistines take you away.’ Samson said, ‘Promise me that you will not kill me yourselves.’

13They said, ‘We agree. We will only tie you up and give you to them. We promise that we will not kill you.’ So they tied him up with two new ropes. They took him with them away from the cave.
