Judges 16:10-12

10Delilah said to Samson, ‘You have deceived me as if I was a fool! Tell me the truth! How can someone really make you weak?’

11Samson said to her, ‘They would have to use new ropes that no one has used. If they tie me up with those, I will become weak, like other men.’

12So Delilah took some new ropes and she tied Samson up with them. Some Philistine men were hiding in the room, as they did before. Then she shouted, ‘Samson, the Philistines are here!’ But he broke the ropes off his arms, as if they were thin string.
