Judges 16:13

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 be upon thee, Samson. And there were 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.

14And she fastened it with the pin, and said unto him, The Philistines be upon thee, Samson. And he awaked out of his sleep, and went away with the pin of the beam, and with the web.

15And she said unto him, How canst thou say, I love thee, when thine heart is not with me? thou hast mocked me these three times, and hast not told me wherein thy great strength lieth.
