Judges 16:8-13

8Then the lords of the Philistines brought up to her seven green withes which had not been dried, and she bound him with them. 9Now she had liers-in-wait abiding in the inner chamber. And she said unto him, The Philistines are upon thee, Samson. And he brake the withes, as a string 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 only bind me with new ropes wherewith no work hath been done, then shall I become weak, and be as another man. 12So Delilah took new ropes, and bound him therewith, and said unto him, The Philistines are upon thee, Samson. And the liers-in-wait were abiding in the inner chamber. And he brake them 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.
