Judges 16:9-12

Now she had men lying in ambush in an inner room. And she said to him, “The Philistines are upon you, Samson!” And he broke the cords as a string of tow breaks when it touches fire. So [the secret of] his strength was not discovered. Then Delilah said to Samson, “See now, you have mocked me and told me lies; now please tell me [truthfully] how you may be bound.” He said to her, “If they bind me tightly with new ropes that have not been used, then I will become weak and be like any [other] man.” So Delilah took new ropes and bound him with them and said to him, “The Philistines are upon you, Samson!” And the men lying in ambush were in the inner room. But he snapped the ropes off his arms like [sewing] thread.
