Judges 16:11KJV

9Now men lying in wait, abiding with her in the chamber. And she said unto him, The Philistines upon thee, Samson. And he brake the withs, as a thread of tow is broken when it toucheth the fire. So his strength was not known.

10And Delilah said unto Samson, Behold, thou hast mocked me, and told me lies: now tell me, I pray thee, wherewith thou mightest be bound.

11And he said unto her, If they bind me fast with new ropes that never were occupied, then shall I be weak, and be as another man.

12Delilah therefore took new ropes, and bound him therewith, and said unto him, The Philistines upon thee, Samson. And liers in wait abiding in the chamber. And he brake them from off his arms like a thread.

13And Delilah said unto Samson, Hitherto thou hast mocked me, and told me lies: tell me wherewith thou mightest be bound. And he said unto her, If thou weavest the seven locks of my head with the web.
